pam_mysql.so

[Nick Smith]

I know this isnt a specific cyrus error, but im not getting anywhere on 
other mailing lists or googling and was hoping that maybe someone on 
this list has had the same error at some time and would be able to tell 
me how to fix it.

Im running SLES 9, with postfix/cyrus/web-cyradm/squirrelmail, for the 
most part its working, i can log into web-cyradm and create domains and 
user accounts, but when the users try to login via squirrelmail i get 
this error in the logs:

It seems im missing the pam_mysql.so, i have confirmed that it is no 
where to be found on the system.  I have installed every package i an 
think of to get that file, pam-devel etc and still cant seem to find 
where that file comes from or what i need to install to get it.

Has anyone else ran into this problem on SLES9?  Can anyone help shed a 
little light on this for me?

Thanks for any and all help.
