To deal with this in a more clean manner, I rebuilt
security/cyrus-sasl23 with the following OPTIONS unchecked:

OTP
NTLM

saslauthd isn't in use/installed on this system:

testbox# pkg_info
cyrus-imapd-2.3.16_1 The cyrus mail server, supporting POP3 and IMAP4 protocols
cyrus-sasl-2.1.23   RFC 2222 SASL (Simple Authentication and Security Layer)
db41-4.1.25_4       The Berkeley DB package, revision 4.1
libtool-2.2.6b      Generic shared library support script
perl-5.10.1_1       Practical Extraction and Report Language
portaudit-0.5.15    Checks installed ports against a list of security vulnerabi
rsync-3.0.7         A network file distribution/synchronization utility
vim-lite-7.2.411    Vi "workalike", with many additional features (Lite package

Same situation:

testbox# cyradm localhost
Password:
Login disabled.
cyradm: cannot authenticate to server with  as root

all.log:

Jul 16 05:13:19 testbox master[10873]: about to exec /usr/local/cyrus/bin/imapd

Jul 16 05:13:23 testbox kernel: Jul 16 05:13:23 testbox perl: No worthy mechs found

It looks like authentication isn't working, probably because I haven't
added any users into the SASL authentication DB.  I believe saslauthd
can also solve this (allowing use of things like /etc/master.passwd
for authentication, as well as other frameworks), but it doesn't look
like it's required.

When I did "make install" for security/cyrus-sasl23, I saw this
message near the end:

You can use sasldb2 for authentication, to add users use:

        saslpasswd2 -c username

So I tried doing exactly that:

testbox# saslpasswd2 -c root
Password:
Again (for verification):
testbox#

Now let's try cyradm again.  Note that at this point I *have not*
entered a password below:

testbox# cyradm localhost
Password:

I immediately see this in syslog:

Jul 16 05:19:47 testbox imap[10881]: accepted connection
Jul 16 05:19:47 testbox perl: GSSAPI Error:  Miscellaneous failure (see text) (unknown mech-code 2 for mech unknown)
Jul 16 05:19:47 testbox perl: DIGEST-MD5 client step 2

Now if I enter the correct password, I get a new prompt:

localhost>

And syslog then shows:

Jul 16 05:21:06 testbox imap[10881]: IOERROR: opening /var/imap/user_deny.db: No such file or directory
Jul 16 05:21:06 testbox perl: DIGEST-MD5 client step 3
Jul 16 05:21:06 testbox imap[10881]: login: localhost [127.0.0.1] root DIGEST-MD5 User logged in
Jul 16 05:21:06 testbox imap[10881]: IOERROR: opening /var/imap/user_deny.db: No such file or directory

So it looks like SASL-wise things are functioning correctly, but GSSAPI
isn't in use (you can see from the error it spits out above).

I think we need the OP of the PR[1], Mikhail T., to chime in here with his
setup.
