pam and ssh

[Daniel Graupner]

Hello,

I'm using pam_mysql for Password-Authentication. It works well with 
apache and samba. But ssh is a bit strange.

I did the following changes to the configfile /etc/pam.conf:
# OpenSSH with PAM support requires similar modules.  The session one is
# a bit strange, though...
sshd    auth    sufficient      pam_skey.so
sshd    auth    sufficient      pam_opie.so                     
no_fake_prompts
#sshd   auth    requisite       pam_opieaccess.so
#sshd   auth    sufficient      pam_kerberosIV.so               
try_first_pass
#sshd   auth    sufficient      pam_krb5.so                     
try_first_pass
#pam_unix durch mysql ersetzen
#sshd   auth    required        pam_unix.so                     
try_first_pass
sshd    auth    required        /usr/local/lib/pam_mysql.so     
host=filer ...
sshd    account required        /usr/local/lib/pam_mysql.so     
host=filer ...
sshd    account required        pam_unix.so
#sshd   password required       pam_permit.so
sshd    session required        pam_permit.so

Hmm, I really don't know what each line stands for.
The corresponding user in passwd exists (without password...this is 
stored in mysql).
After failed Authentication the following lines appeared in 
/var/log/messages:

Any Suggests?

Thanks, Daniel.
