+This is a forward-port of the OpenSSH LPK support patch.
+
+It adds support for storing OpenSSH public keys in LDAP. It also supports
+grouping of machines in the LDAP data to limit users to specific machines.
+
+The latest homepage for the LPK project is:
+http://code.google.com/p/openssh-lpk/
+
+The 0.3.10 version of the patch includes a fix for 64-bit platforms, as
+discovered by Gentoo, where the bind timeout and search timeout values were not
+being parsed correctly: http://bugs.gentoo.org/210110
+
+Forward-ported-from: openssh-lpk-5.1p1-0.3.9.patch

++OpenSSH LDAP keystore Patch
++===========================
++
++NOTE: these notes are a transcript of a specific installation
++ they work for me, your specifics may be different!
++ from John Lane March 17th 2005 john at lane.uk.net
++
++This is a patch to OpenSSH 4.0p1 to allow it to obtain users' public keys
++from their LDAP record as an alternative to ~/.ssh/authorized_keys.
++
++(Assuming here that necessary build stuff is in $BUILD)
++
++cd $BUILD/openssh-4.0p1
++patch -Np1 -i $BUILD/openssh-lpk-4.0p1-0.3.patch
++mkdir -p /var/empty &&
++./configure --prefix=/usr --sysconfdir=/etc/ssh \
++ --libexecdir=/usr/sbin --with-md5-passwords --with-pam \
++ --with-libs="-lldap" --with-cppflags="-DWITH_LDAP_PUBKEY"
++Now do.
++make &&
++make install
++
++Add the following config to /etc/ssh/ssh_config
++UseLPK yes
++LpkServers ldap://myhost.mydomain.com
++LpkUserDN ou=People,dc=mydomain,dc=com
++
++We need to tell sshd about the SSL keys during boot, as root's
++environment does not exist at that time. Edit /etc/rc.d/init.d/sshd.
++Change the startup code from this:
++ echo "Starting SSH Server..."
++ loadproc /usr/sbin/sshd
++ ;;
++to this:
++ echo "Starting SSH Server..."
++ LDAPRC="/root/.ldaprc" loadproc /usr/sbin/sshd
++ ;;
++
++Re-start the sshd daemon:
++/etc/rc.d/init.d/sshd restart
++
++Install the additional LDAP schema
++cp $BUILD/openssh-lpk-0.2.schema /etc/openldap/schema/openssh.schema
++
++Now add the openSSH LDAP schema to /etc/openldap/slapd.conf:
++Add the following to the end of the existing block of schema includes
++include /etc/openldap/schema/openssh.schema
++
++Re-start the LDAP server:
++/etc/rc.d/init.d/slapd restart
++
++To add one or more public keys to a user, eg "testuser" :
++ldapsearch -x -W -Z -LLL -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
++"uid=testuser,ou=People,dc=mydomain,dc=com" > /tmp/testuser
++
++append the following to this /tmp/testuser file
++objectclass: ldapPublicKey
++sshPublicKey: ssh-rsa
++AAAAB3NzaC1yc2EAAAABJQAAAIB3dsrwqXqD7E4zYYrxwdDKBUQxKMioXy9pxFVai64kAPxjU9KS

++7eZE/gVbn2UQkQq7+kdDTS2yXV6VnC52N/kKLG3ciBkBAw== General Purpose RSA Key
++
++Then do a modify:
++ldapmodify -x -D "uid=testuser,ou=People,dc=mydomain,dc=com" -W -f
++/tmp/testuser -Z
++Enter LDAP Password:
++modifying entry "uid=testuser,ou=People,dc=mydomain,dc=com"
++And check the modify is ok:
++ldapsearch -x -W -Z -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
++"uid=testuser,ou=People,dc=mydomain,dc=com"
++Enter LDAP Password:
++# extended LDIF
++#
++# LDAPv3
++# base <uid=testuser,ou=People,dc=mydomain,dc=com> with scope sub
++# filter: (objectclass=*)
++# requesting: ALL
++#
++
++# testuser, People, mydomain.com
++dn: uid=testuser,ou=People,dc=mydomain,dc=com
++uid: testuser
++cn: testuser
++objectClass: account
++objectClass: posixAccount
++objectClass: top
++objectClass: shadowAccount
++objectClass: ldapPublicKey
++shadowLastChange: 12757
++shadowMax: 99999
++shadowWarning: 7
++loginShell: /bin/bash
++uidNumber: 9999
++gidNumber: 501
++homeDirectory: /home/testuser
++userPassword:: e1NTSEF9UDgwV1hnM1VjUDRJK0k1YnFiL1d4ZUJObXlZZ3Z3UTU=
++sshPublicKey: ssh-rsa

++
++# search result
++search: 3
++result: 0 Success
++
++# numResponses: 2
++# numEntries: 1
++
++Now start a ssh session to user "testuser" from usual ssh client (e.g.
++puTTY). Login should succeed.

++
++purposes of this patch:
++
++This patch would help to have authentication centralization policy
++using ssh public key authentication.
++This patch could be an alternative to other "secure" authentication system
++working in a similar way (Kerberos, SecurID, etc...), except the fact
++that it's based on OpenSSH and its public key abilities.
++
++>> FYI: <<
++'uid': means unix accounts existing on the current server
++'lpkServerGroup:' mean server group configured on the current server ('lpkServerGroup' in sshd_config)
++
++example schema:
++
++
++ server1 (uid: eau,rival,toto) (lpkServerGroup: unix)
++ ___________ /
++ / \ --- - server3 (uid: eau, titi) (lpkServerGroup: unix)
++ | LDAP Server | \
++ | eau ,rival | server2 (uid: rival, eau) (lpkServerGroup: unix)
++ | titi ,toto |
++ | userx,.... | server5 (uid: eau) (lpkServerGroup: mail)
++ \___________/ \ /
++ ----- - server4 (uid: eau, rival) (no group configured)
++ \
++ etc...
++
++- WHAT WE NEED :
++
++ * configured LDAP server somewhere on the network (i.e. OpenLDAP)
++ * patched sshd (with this patch ;)
++ * LDAP user(/group) entry (look at users.ldif (& groups.ldif)):
++ User entry:
++ - attached to the 'ldapPublicKey' objectclass
++ - attached to the 'posixAccount' objectclass
++ - with a filled 'sshPublicKey' attribute
++ Example:
++ dn: uid=eau,ou=users,dc=cuckoos,dc=net
++ objectclass: top
++ objectclass: person
++ objectclass: organizationalPerson
++ objectclass: posixAccount
++ objectclass: ldapPublicKey
++ description: Eric AUGE Account
++ userPassword: blah
++ cn: Eric AUGE
++ sn: Eric AUGE
++ uid: eau
++ uidNumber: 1034
++ gidNumber: 1
++ homeDirectory: /export/home/eau
++ sshPublicKey: ssh-dss AAAAB3...
++ sshPublicKey: ssh-dss AAAAM5...
++
++ Group entry:
++ - attached to the 'posixGroup' objectclass
++ - with a 'cn' groupname attribute
++ - with multiple 'memberUid' attributes filled with usernames allowed in this group
++ Example:
++ # few members
++ dn: cn=unix,ou=groups,dc=cuckoos,dc=net
++ objectclass: top
++ objectclass: posixGroup
++ description: Unix based servers group
++ cn: unix
++ gidNumber: 1002
++ memberUid: eau
++ memberUid: user1
++ memberUid: user2
++
++
++- HOW IT WORKS :
++
++ * without patch
++ If a user wants to authenticate to log in a server the sshd, will first look for authentication method allowed (RSAauth,kerberos,etc..)
++ and if RSAauth and tickets based auth fails, it will fallback to standard password authentication (if enabled).
++
++ * with the patch
++ If a user want to authenticate to log in a server, the sshd will first look for auth method including LDAP pubkey, if the ldappubkey options is enabled.
++ It will do an ldapsearch to get the public key directly from the LDAP instead of reading it from the server filesystem.
++ (usually in $HOME/.ssh/authorized_keys)
++
++ If groups are enabled, it will also check if the user that wants to login is in the group of the server he is trying to log into.
++ If it fails, it falls back on RSA auth files ($HOME/.ssh/authorized_keys), etc.. and finally to standard password authentication (if enabled).
++
++ 7 tokens are added to sshd_config :
++ # here is the new patched ldap related tokens
++ # entries in your LDAP must be posixAccount & strongAuthenticationUser & posixGroup
++ UseLPK yes # look the pub key into LDAP
++ LpkServers ldap://10.31.32.5/ ldap://10.31.32.4 ldap://10.31.32.3 # which LDAP server for users ? (URL format)
++ LpkUserDN ou=users,dc=foobar,dc=net # which base DN for users ?
++ LpkGroupDN ou=groups,dc=foobar,dc=net # which base DN for groups ?
++ LpkBindDN cn=manager,dc=foobar,dc=net # which bind DN ?
++ LpkBindPw asecret # bind DN credidentials
++ LpkServerGroup agroupname # the group the server is part of
++
++ Right now i'm using anonymous binding to get public keys, because getting public keys of someone doesn't impersonate him¸ but there is some
++ flaws you have to take care of.
++
++- HOW TO INSERT A USER/KEY INTO AN LDAP ENTRY
++
++ * my way (there is plenty :)
++ - create ldif file (i.e. users.ldif)
++ - cat ~/.ssh/id_dsa.pub OR cat ~/.ssh/id_rsa.pub OR cat ~/.ssh/identity.pub
++ - my way in 4 steps :
++ Example:
++
++ # you add this to the user entry in the LDIF file :
++ [...]
++ objectclass: posixAccount
++ objectclass: ldapPublicKey
++ [...]
++ sshPubliKey: ssh-dss AAAABDh12DDUR2...
++ [...]
++
++ # insert your entry and you're done :)
++ ldapadd -D balblabla -w bleh < file.ldif
++
++ all standard options can be present in the 'sshPublicKey' attribute.
++
++- WHY :
++
++ Simply because, i was looking for a way to centralize all sysadmins authentication, easily, without completely using LDAP
++ as authentication method (like pam_ldap etc..).
++
++ After looking into Kerberos, SecurID, and other centralized secure authentications systems, the use of RSA and LDAP to get
++ public key for authentication allows us to control who has access to which server (the user needs an account and to be in 'strongAuthenticationUser'
++ objectclass within LDAP and part of the group the SSH server is in).
++
++ Passwords update are no longer a nightmare for a server farm (key pair passphrase is stored on each user's box and private key is locally encrypted using his passphrase
++ so each user can change it as much as he wants).
++
++ Blocking a user account can be done directly from the LDAP (if sshd is using RSAAuth + ldap only).
++
++- RULES :
++ Entry in the LDAP server must respect 'posixAccount' and 'ldapPublicKey' which are defined in core.schema.
++ and the additionnal lpk.schema.
++
++ This patch could allow a smooth transition between standard auth (/etc/passwd) and complete LDAP based authentication
++ (pamldap, nss_ldap, etc..).
++
++ This can be an alternative to other (old?/expensive?) authentication methods (Kerberos/SecurID/..).
++
++ Referring to schema at the beginning of this file if user 'eau' is only in group 'unix'
++ 'eau' would ONLY access 'server1', 'server2', 'server3' AND 'server4' BUT NOT 'server5'.
++ If you then modify the LDAP 'mail' group entry to add 'memberUid: eau' THEN user 'eau' would be able
++ to log in 'server5' (i hope you got the idea, my english is bad :).
++
++ Each server's sshd is patched and configured to ask the public key and the group infos in the LDAP
++ server.
++ When you want to allow a new user to have access to the server parc, you just add him an account on
++ your servers, you add his public key into his entry on the LDAP server, it's done.
++
++ Because sshds are looking public keys into the LDAP directly instead of a file ($HOME/.ssh/authorized_keys).
++
++ When the user needs to change his passphrase he can do it directly from his workstation by changing
++ his own key set lock passphrase, and all servers are automatically aware.
++
++ With a CAREFUL LDAP server configuration you could allow a user to add/delete/modify his own entry himself
++ so he can add/modify/delete himself his public key when needed.
++
++ FLAWS :
++ LDAP must be well configured, getting the public key of some user is not a problem, but if anonymous LDAP
++ allow write to users dn, somebody could replace someuser's public key by its own and impersonate some
++ of your users in all your server farm be VERY CAREFUL.
++
++ MITM attack when sshd is requesting the public key, could lead to a compromise of your servers allowing login
++ as the impersonnated user.
++
++ If LDAP server is down then, fallback on passwd auth.
++
++ the ldap code part has not been well audited yet.

++>> FYI: <<
++Multiple 'sshPublicKey' in a user entry are allowed, as well as multiple 'memberUid' attributes in a group entry
++
++- COMPILING:
++ 1. Apply the patch
++ 2. ./configure --with-your-options --with-ldap=/prefix/to/ldap_libs_and_includes
++ 3. make
++ 4. it's done.

-+Notes:
-+
-+MULTI-THREADED CIPHER:
-+The AES cipher in CTR mode has been multithreaded (MTR-AES-CTR). This will allow ssh installations
-+on hosts with multiple cores to use more than one processing core during encryption.
-+Tests have show significant throughput performance increases when using MTR-AES-CTR up
-+to and including a full gigabit per second on quad core systems. It should be possible to
-+achieve full line rate on dual core systems but OS and data management overhead makes this
-+more difficult to achieve. The cipher stream from MTR-AES-CTR is entirely compatible with single
-+thread AES-CTR (ST-AES-CTR) implementations and should be 100% backward compatible. Optimal
-+performance requires the MTR-AES-CTR mode be enabled on both ends of the connection.
-+The MTR-AES-CTR replaces ST-AES-CTR and is used in exactly the same way with the same
-+nomenclature.
-+Use examples: ssh -caes128-ctr you at host.com
-+ scp -oCipher=aes256-ctr file you at host.com:~/file
-+
-+NONE CIPHER:
-+To use the NONE option you must have the NoneEnabled switch set on the server and
-+you *must* have *both* NoneEnabled and NoneSwitch set to yes on the client. The NONE
-+feature works with ALL ssh subsystems (as far as we can tell) *AS LONG AS* a tty is not
-+spawned. If a user uses the -T switch to prevent a tty being created the NONE cipher will
-+be disabled.
-+
-+The performance increase will only be as good as the network and TCP stack tuning
-+on the reciever side of the connection allows. As a rule of thumb a user will need
-+at least 10Mb/s connection with a 100ms RTT to see a doubling of performance. The
-+HPN-SSH home page describes this in greater detail.
-+
-+http://www.psc.edu/networking/projects/hpn-ssh
-+
-+BUFFER SIZES:
-+
-+If HPN is disabled the receive buffer size will be set to the
-+OpenSSH default of 64K.
-+
-+If an HPN system connects to a nonHPN system the receive buffer will
-+be set to the HPNBufferSize value. The default is 2MB but user adjustable.
-+
-+If an HPN to HPN connection is established a number of different things might
-+happen based on the user options and conditions.
-+
-+Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set
-+HPN Buffer Size = up to 64MB
-+This is the default state. The HPN buffer size will grow to a maximum of 64MB
-+as the TCP receive buffer grows. The maximum HPN Buffer size of 64MB is
-+geared towards 10GigE transcontinental connections.
-+
-+Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set
-+HPN Buffer Size = TCP receive buffer value.
-+Users on non-autotuning systesm should disable TCPRcvBufPoll in the
-+ssh_cofig and sshd_config
-+
-+Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set
-+HPN Buffer Size = minmum of TCP receive buffer and HPNBufferSize.
-+This would be the system defined TCP receive buffer (RWIN).
-+
-+Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf SET
-+HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize.
-+Generally there is no need to set both.
-+
-+Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set
-+HPN Buffer Size = grows to HPNBufferSize
-+The buffer will grow up to the maximum size specified here.
-+
-+Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf SET
-+HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize.
-+Generally there is no need to set both of these, especially on autotuning
-+systems. However, if the users wishes to override the autotuning this would be
-+one way to do it.
-+
-+Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf SET
-+HPN Buffer Size = TCPRcvBuf.
-+This will override autotuning and set the TCP recieve buffer to the user defined
-+value.
-+
-+
-+HPN Specific Configuration options
-+
-+TcpRcvBuf=[int]KB client
-+ set the TCP socket receive buffer to n Kilobytes. It can be set up to the
-+maximum socket size allowed by the system. This is useful in situations where
-+the tcp receive window is set low but the maximum buffer size is set
-+higher (as is typical). This works on a per TCP connection basis. You can also
-+use this to artifically limit the transfer rate of the connection. In these
-+cases the throughput will be no more than n/RTT. The minimum buffer size is 1KB.
-+Default is the current system wide tcp receive buffer size.
-+
-+TcpRcvBufPoll=[yes/no] client/server
-+ enable of disable the polling of the tcp receive buffer through the life
-+of the connection. You would want to make sure that this option is enabled
-+for systems making use of autotuning kernels (linux 2.4.24+, 2.6, MS Vista)
-+default is yes.
-+
-+NoneEnabled=[yes/no] client/server
-+ enable or disable the use of the None cipher. Care must always be used
-+when enabling this as it will allow users to send data in the clear. However,
-+it is important to note that authentication information remains encrypted
-+even if this option is enabled. Set to no by default.
-+
-+NoneSwitch=[yes/no] client
-+ Switch the encryption cipher being used to the None cipher after
-+authentication takes place. NoneEnabled must be enabled on both the client
-+and server side of the connection. When the connection switches to the NONE
-+cipher a warning is sent to STDERR. The connection attempt will fail with an
-+error if a client requests a NoneSwitch from the server that does not explicitly
-+have NoneEnabled set to yes. Note: The NONE cipher cannot be used in
-+interactive (shell) sessions and it will fail silently. Set to no by default.
-+
-+HPNDisabled=[yes/no] client/server
-+ In some situations, such as transfers on a local area network, the impact
-+of the HPN code produces a net decrease in performance. In these cases it is
-+helpful to disable the HPN functionality. By default HPNDisabled is set to no.
-+
-+HPNBufferSize=[int]KB client/server
-+ This is the default buffer size the HPN functionality uses when interacting
-+with nonHPN SSH installations. Conceptually this is similar to the TcpRcvBuf
-+option as applied to the internal SSH flow control. This value can range from
-+1KB to 64MB (1-65536). Use of oversized or undersized buffers can cause performance
-+problems depending on the length of the network path. The default size of this buffer
-+is 2MB.
-+
-+
-+Credits: This patch was conceived, designed, and led by Chris Rapier (rapier at psc.edu)
-+ The majority of the actual coding for versions up to HPN12v1 was performed
-+ by Michael Stevens (mstevens at andrew.cmu.edu). The MT-AES-CTR cipher was
-+ implemented by Ben Bennet (ben at psc.edu). This work was financed, in part,
-+ by Cisco System, Inc., the National Library of Medicine,
-+ and the National Science Foundation.

++Notes:
++
++MULTI-THREADED CIPHER:
++The AES cipher in CTR mode has been multithreaded (MTR-AES-CTR). This will allow ssh installations
++on hosts with multiple cores to use more than one processing core during encryption.
++Tests have show significant throughput performance increases when using MTR-AES-CTR up
++to and including a full gigabit per second on quad core systems. It should be possible to
++achieve full line rate on dual core systems but OS and data management overhead makes this
++more difficult to achieve. The cipher stream from MTR-AES-CTR is entirely compatible with single
++thread AES-CTR (ST-AES-CTR) implementations and should be 100% backward compatible. Optimal
++performance requires the MTR-AES-CTR mode be enabled on both ends of the connection.
++The MTR-AES-CTR replaces ST-AES-CTR and is used in exactly the same way with the same
++nomenclature.
++Use examples: ssh -caes128-ctr you at host.com
++ scp -oCipher=aes256-ctr file you at host.com:~/file
++
++NONE CIPHER:
++To use the NONE option you must have the NoneEnabled switch set on the server and
++you *must* have *both* NoneEnabled and NoneSwitch set to yes on the client. The NONE
++feature works with ALL ssh subsystems (as far as we can tell) *AS LONG AS* a tty is not
++spawned. If a user uses the -T switch to prevent a tty being created the NONE cipher will
++be disabled.
++
++The performance increase will only be as good as the network and TCP stack tuning
++on the reciever side of the connection allows. As a rule of thumb a user will need
++at least 10Mb/s connection with a 100ms RTT to see a doubling of performance. The
++HPN-SSH home page describes this in greater detail.
++
++http://www.psc.edu/networking/projects/hpn-ssh
++
++BUFFER SIZES:
++
++If HPN is disabled the receive buffer size will be set to the
++OpenSSH default of 64K.
++
++If an HPN system connects to a nonHPN system the receive buffer will
++be set to the HPNBufferSize value. The default is 2MB but user adjustable.
++
++If an HPN to HPN connection is established a number of different things might
++happen based on the user options and conditions.
++
++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set
++HPN Buffer Size = up to 64MB
++This is the default state. The HPN buffer size will grow to a maximum of 64MB
++as the TCP receive buffer grows. The maximum HPN Buffer size of 64MB is
++geared towards 10GigE transcontinental connections.
++
++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set
++HPN Buffer Size = TCP receive buffer value.
++Users on non-autotuning systesm should disable TCPRcvBufPoll in the
++ssh_cofig and sshd_config
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf NOT Set
++HPN Buffer Size = minmum of TCP receive buffer and HPNBufferSize.
++This would be the system defined TCP receive buffer (RWIN).
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll disabled, TCPRcvBuf SET
++HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize.
++Generally there is no need to set both.
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf NOT Set
++HPN Buffer Size = grows to HPNBufferSize
++The buffer will grow up to the maximum size specified here.
++
++Conditions: HPNBufferSize SET, TCPRcvBufPoll enabled, TCPRcvBuf SET
++HPN Buffer Size = minmum of TCPRcvBuf and HPNBufferSize.
++Generally there is no need to set both of these, especially on autotuning
++systems. However, if the users wishes to override the autotuning this would be
++one way to do it.
++
++Conditions: HPNBufferSize NOT Set, TCPRcvBufPoll enabled, TCPRcvBuf SET
++HPN Buffer Size = TCPRcvBuf.
++This will override autotuning and set the TCP recieve buffer to the user defined
++value.
++
++
++HPN Specific Configuration options
++
++TcpRcvBuf=[int]KB client
++ set the TCP socket receive buffer to n Kilobytes. It can be set up to the
++maximum socket size allowed by the system. This is useful in situations where
++the tcp receive window is set low but the maximum buffer size is set
++higher (as is typical). This works on a per TCP connection basis. You can also
++use this to artifically limit the transfer rate of the connection. In these
++cases the throughput will be no more than n/RTT. The minimum buffer size is 1KB.
++Default is the current system wide tcp receive buffer size.
++
++TcpRcvBufPoll=[yes/no] client/server
++ enable of disable the polling of the tcp receive buffer through the life
++of the connection. You would want to make sure that this option is enabled
++for systems making use of autotuning kernels (linux 2.4.24+, 2.6, MS Vista)
++default is yes.
++
++NoneEnabled=[yes/no] client/server
++ enable or disable the use of the None cipher. Care must always be used
++when enabling this as it will allow users to send data in the clear. However,
++it is important to note that authentication information remains encrypted
++even if this option is enabled. Set to no by default.
++
++NoneSwitch=[yes/no] client
++ Switch the encryption cipher being used to the None cipher after
++authentication takes place. NoneEnabled must be enabled on both the client
++and server side of the connection. When the connection switches to the NONE
++cipher a warning is sent to STDERR. The connection attempt will fail with an
++error if a client requests a NoneSwitch from the server that does not explicitly
++have NoneEnabled set to yes. Note: The NONE cipher cannot be used in
++interactive (shell) sessions and it will fail silently. Set to no by default.
++
++HPNDisabled=[yes/no] client/server
++ In some situations, such as transfers on a local area network, the impact
++of the HPN code produces a net decrease in performance. In these cases it is
++helpful to disable the HPN functionality. By default HPNDisabled is set to no.
++
++HPNBufferSize=[int]KB client/server
++ This is the default buffer size the HPN functionality uses when interacting
++with nonHPN SSH installations. Conceptually this is similar to the TcpRcvBuf
++option as applied to the internal SSH flow control. This value can range from
++1KB to 64MB (1-65536). Use of oversized or undersized buffers can cause performance
++problems depending on the length of the network path. The default size of this buffer
++is 2MB.
++
++
++Credits: This patch was conceived, designed, and led by Chris Rapier (rapier at psc.edu)
++ The majority of the actual coding for versions up to HPN12v1 was performed
++ by Michael Stevens (mstevens at andrew.cmu.edu). The MT-AES-CTR cipher was
++ implemented by Ben Bennet (ben at psc.edu). This work was financed, in part,
++ by Cisco System, Inc., the National Library of Medicine,
++ and the National Science Foundation.

-+purposes of this patch:
-+
-+This patch would help to have authentication centralization policy
-+using ssh public key authentication.
-+This patch could be an alternative to other "secure" authentication system
-+working in a similar way (Kerberos, SecurID, etc...), except the fact
-+that it's based on OpenSSH and its public key abilities.
-+
-+>> FYI: <<
-+'uid': means unix accounts existing on the current server
-+'lpkServerGroup:' mean server group configured on the current server ('lpkServerGroup' in sshd_config)
-+
-+example schema:
-+
-+
-+ server1 (uid: eau,rival,toto) (lpkServerGroup: unix)
-+ ___________ /
-+ / \ --- - server3 (uid: eau, titi) (lpkServerGroup: unix)
-+ | LDAP Server | \
-+ | eau ,rival | server2 (uid: rival, eau) (lpkServerGroup: unix)
-+ | titi ,toto |
-+ | userx,.... | server5 (uid: eau) (lpkServerGroup: mail)
-+ \___________/ \ /
-+ ----- - server4 (uid: eau, rival) (no group configured)
-+ \
-+ etc...
-+
-+- WHAT WE NEED :
-+
-+ * configured LDAP server somewhere on the network (i.e. OpenLDAP)
-+ * patched sshd (with this patch ;)
-+ * LDAP user(/group) entry (look at users.ldif (& groups.ldif)):
-+ User entry:
-+ - attached to the 'ldapPublicKey' objectclass
-+ - attached to the 'posixAccount' objectclass
-+ - with a filled 'sshPublicKey' attribute
-+ Example:
-+ dn: uid=eau,ou=users,dc=cuckoos,dc=net
-+ objectclass: top
-+ objectclass: person
-+ objectclass: organizationalPerson
-+ objectclass: posixAccount
-+ objectclass: ldapPublicKey
-+ description: Eric AUGE Account
-+ userPassword: blah
-+ cn: Eric AUGE
-+ sn: Eric AUGE
-+ uid: eau
-+ uidNumber: 1034
-+ gidNumber: 1
-+ homeDirectory: /export/home/eau
-+ sshPublicKey: ssh-dss AAAAB3...
-+ sshPublicKey: ssh-dss AAAAM5...
-+
-+ Group entry:
-+ - attached to the 'posixGroup' objectclass
-+ - with a 'cn' groupname attribute
-+ - with multiple 'memberUid' attributes filled with usernames allowed in this group
-+ Example:
-+ # few members
-+ dn: cn=unix,ou=groups,dc=cuckoos,dc=net
-+ objectclass: top
-+ objectclass: posixGroup
-+ description: Unix based servers group
-+ cn: unix
-+ gidNumber: 1002
-+ memberUid: eau
-+ memberUid: user1
-+ memberUid: user2
-+
-+
-+- HOW IT WORKS :
-+
-+ * without patch
-+ If a user wants to authenticate to log in a server the sshd, will first look for authentication method allowed (RSAauth,kerberos,etc..)
-+ and if RSAauth and tickets based auth fails, it will fallback to standard password authentication (if enabled).
-+
-+ * with the patch
-+ If a user want to authenticate to log in a server, the sshd will first look for auth method including LDAP pubkey, if the ldappubkey options is enabled.
-+ It will do an ldapsearch to get the public key directly from the LDAP instead of reading it from the server filesystem.
-+ (usually in $HOME/.ssh/authorized_keys)
-+
-+ If groups are enabled, it will also check if the user that wants to login is in the group of the server he is trying to log into.
-+ If it fails, it falls back on RSA auth files ($HOME/.ssh/authorized_keys), etc.. and finally to standard password authentication (if enabled).
-+
-+ 7 tokens are added to sshd_config :
-+ # here is the new patched ldap related tokens
-+ # entries in your LDAP must be posixAccount & strongAuthenticationUser & posixGroup
-+ UseLPK yes # look the pub key into LDAP
-+ LpkServers ldap://10.31.32.5/ ldap://10.31.32.4 ldap://10.31.32.3 # which LDAP server for users ? (URL format)
-+ LpkUserDN ou=users,dc=foobar,dc=net # which base DN for users ?
-+ LpkGroupDN ou=groups,dc=foobar,dc=net # which base DN for groups ?
-+ LpkBindDN cn=manager,dc=foobar,dc=net # which bind DN ?
-+ LpkBindPw asecret # bind DN credidentials
-+ LpkServerGroup agroupname # the group the server is part of
-+
-+ Right now i'm using anonymous binding to get public keys, because getting public keys of someone doesn't impersonate him¸ but there is some
-+ flaws you have to take care of.
-+
-+- HOW TO INSERT A USER/KEY INTO AN LDAP ENTRY
-+
-+ * my way (there is plenty :)
-+ - create ldif file (i.e. users.ldif)
-+ - cat ~/.ssh/id_dsa.pub OR cat ~/.ssh/id_rsa.pub OR cat ~/.ssh/identity.pub
-+ - my way in 4 steps :
-+ Example:
-+
-+ # you add this to the user entry in the LDIF file :
-+ [...]
-+ objectclass: posixAccount
-+ objectclass: ldapPublicKey
-+ [...]
-+ sshPubliKey: ssh-dss AAAABDh12DDUR2...
-+ [...]
-+
-+ # insert your entry and you're done :)
-+ ldapadd -D balblabla -w bleh < file.ldif
-+
-+ all standard options can be present in the 'sshPublicKey' attribute.
-+
-+- WHY :
-+
-+ Simply because, i was looking for a way to centralize all sysadmins authentication, easily, without completely using LDAP
-+ as authentication method (like pam_ldap etc..).
-+
-+ After looking into Kerberos, SecurID, and other centralized secure authentications systems, the use of RSA and LDAP to get
-+ public key for authentication allows us to control who has access to which server (the user needs an account and to be in 'strongAuthenticationUser'
-+ objectclass within LDAP and part of the group the SSH server is in).
-+
-+ Passwords update are no longer a nightmare for a server farm (key pair passphrase is stored on each user's box and private key is locally encrypted using his passphrase
-+ so each user can change it as much as he wants).
-+
-+ Blocking a user account can be done directly from the LDAP (if sshd is using RSAAuth + ldap only).
-+
-+- RULES :
-+ Entry in the LDAP server must respect 'posixAccount' and 'ldapPublicKey' which are defined in core.schema.
-+ and the additionnal lpk.schema.
-+
-+ This patch could allow a smooth transition between standard auth (/etc/passwd) and complete LDAP based authentication
-+ (pamldap, nss_ldap, etc..).
-+
-+ This can be an alternative to other (old?/expensive?) authentication methods (Kerberos/SecurID/..).
-+
-+ Referring to schema at the beginning of this file if user 'eau' is only in group 'unix'
-+ 'eau' would ONLY access 'server1', 'server2', 'server3' AND 'server4' BUT NOT 'server5'.
-+ If you then modify the LDAP 'mail' group entry to add 'memberUid: eau' THEN user 'eau' would be able
-+ to log in 'server5' (i hope you got the idea, my english is bad :).
-+
-+ Each server's sshd is patched and configured to ask the public key and the group infos in the LDAP
-+ server.
-+ When you want to allow a new user to have access to the server parc, you just add him an account on
-+ your servers, you add his public key into his entry on the LDAP server, it's done.
-+
-+ Because sshds are looking public keys into the LDAP directly instead of a file ($HOME/.ssh/authorized_keys).
-+
-+ When the user needs to change his passphrase he can do it directly from his workstation by changing
-+ his own key set lock passphrase, and all servers are automatically aware.
-+
-+ With a CAREFUL LDAP server configuration you could allow a user to add/delete/modify his own entry himself
-+ so he can add/modify/delete himself his public key when needed.
-+
-+ FLAWS :
-+ LDAP must be well configured, getting the public key of some user is not a problem, but if anonymous LDAP
-+ allow write to users dn, somebody could replace someuser's public key by its own and impersonate some
-+ of your users in all your server farm be VERY CAREFUL.
-+
-+ MITM attack when sshd is requesting the public key, could lead to a compromise of your servers allowing login
-+ as the impersonnated user.
-+
-+ If LDAP server is down then, fallback on passwd auth.
-+
-+ the ldap code part has not been well audited yet.

-+
-+>> FYI: <<
-+Multiple 'sshPublicKey' in a user entry are allowed, as well as multiple 'memberUid' attributes in a group entry
-+
-+- COMPILING:
-+ 1. Apply the patch
-+ 2. ./configure --with-your-options --with-ldap=/prefix/to/ldap_libs_and_includes
-+ 3. make
-+ 4. it's done.
-+
-+- BLA :
-+ I hope this could help, and i hope to be clear enough,, or give ideas. questions/comments/improvements are welcome.
-+
-+- TODO :
-+ Redesign differently.

-+OpenSSH LDAP keystore Patch
-+===========================
-+
-+NOTE: these notes are a transcript of a specific installation
-+ they work for me, your specifics may be different!
-+ from John Lane March 17th 2005 john at lane.uk.net
-+
-+This is a patch to OpenSSH 4.0p1 to allow it to obtain users' public keys
-+from their LDAP record as an alternative to ~/.ssh/authorized_keys.
-+
-+(Assuming here that necessary build stuff is in $BUILD)
-+
-+cd $BUILD/openssh-4.0p1
-+patch -Np1 -i $BUILD/openssh-lpk-4.0p1-0.3.patch
-+mkdir -p /var/empty &&
-+./configure --prefix=/usr --sysconfdir=/etc/ssh \
-+ --libexecdir=/usr/sbin --with-md5-passwords --with-pam \
-+ --with-libs="-lldap" --with-cppflags="-DWITH_LDAP_PUBKEY"
-+Now do.
-+make &&
-+make install
-+
-+Add the following config to /etc/ssh/ssh_config
-+UseLPK yes
-+LpkServers ldap://myhost.mydomain.com
-+LpkUserDN ou=People,dc=mydomain,dc=com
-+
-+We need to tell sshd about the SSL keys during boot, as root's
-+environment does not exist at that time. Edit /etc/rc.d/init.d/sshd.
-+Change the startup code from this:
-+ echo "Starting SSH Server..."
-+ loadproc /usr/sbin/sshd
-+ ;;
-+to this:
-+ echo "Starting SSH Server..."
-+ LDAPRC="/root/.ldaprc" loadproc /usr/sbin/sshd
-+ ;;
-+
-+Re-start the sshd daemon:
-+/etc/rc.d/init.d/sshd restart
-+
-+Install the additional LDAP schema
-+cp $BUILD/openssh-lpk-0.2.schema /etc/openldap/schema/openssh.schema
-+
-+Now add the openSSH LDAP schema to /etc/openldap/slapd.conf:
-+Add the following to the end of the existing block of schema includes
-+include /etc/openldap/schema/openssh.schema
-+
-+Re-start the LDAP server:
-+/etc/rc.d/init.d/slapd restart
-+
-+To add one or more public keys to a user, eg "testuser" :
-+ldapsearch -x -W -Z -LLL -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
-+"uid=testuser,ou=People,dc=mydomain,dc=com" > /tmp/testuser
-+
-+append the following to this /tmp/testuser file
-+objectclass: ldapPublicKey
-+sshPublicKey: ssh-rsa
-+AAAAB3NzaC1yc2EAAAABJQAAAIB3dsrwqXqD7E4zYYrxwdDKBUQxKMioXy9pxFVai64kAPxjU9KS

-+7eZE/gVbn2UQkQq7+kdDTS2yXV6VnC52N/kKLG3ciBkBAw== General Purpose RSA Key
-+
-+Then do a modify:
-+ldapmodify -x -D "uid=testuser,ou=People,dc=mydomain,dc=com" -W -f
-+/tmp/testuser -Z
-+Enter LDAP Password:
-+modifying entry "uid=testuser,ou=People,dc=mydomain,dc=com"
-+And check the modify is ok:
-+ldapsearch -x -W -Z -b "uid=testuser,ou=People,dc=mydomain,dc=com" -D
-+"uid=testuser,ou=People,dc=mydomain,dc=com"
-+Enter LDAP Password:
-+# extended LDIF
-+#
-+# LDAPv3
-+# base <uid=testuser,ou=People,dc=mydomain,dc=com> with scope sub
-+# filter: (objectclass=*)
-+# requesting: ALL
-+#
-+
-+# testuser, People, mydomain.com
-+dn: uid=testuser,ou=People,dc=mydomain,dc=com
-+uid: testuser
-+cn: testuser
-+objectClass: account
-+objectClass: posixAccount
-+objectClass: top
-+objectClass: shadowAccount
-+objectClass: ldapPublicKey
-+shadowLastChange: 12757
-+shadowMax: 99999
-+shadowWarning: 7
-+loginShell: /bin/bash
-+uidNumber: 9999
-+gidNumber: 501
-+homeDirectory: /home/testuser
-+userPassword:: e1NTSEF9UDgwV1hnM1VjUDRJK0k1YnFiL1d4ZUJObXlZZ3Z3UTU=

-+# search result
-+search: 3
