Finding missing file (or directory) for pam_mysql

[Chong Yu Meng]

Hi all,

I just setup a new mail server with Postfix+CyrusIMAP+MySQL and it 
mostly works (I am sending this email through the new server). I do, 
however, have a very annoying message that keeps writing to /var/log/warn:

"pam_mysql - something went wrong when invoking crypt() - No such file 
or directory"

If my webmail is open, it logs every minute. It doesn't stop me from 
authenticating correctly, so it is not a show-stopper, and it doesn't 
slow the server down - it is just annoying.

So, I want to find out what file or directory it is looking for, so I 
can shut pam_mysql up. I've been Googling for a day now and I even 
looked at the source code (which just got me more confused). Is there 
some command that I can use to help me discover what the missing file or 
directory is?

Thanks in Advance!
