Here is what my /etc/pam.d/imap file contains:
auth sufficient pam_unix.so
auth required pam_ldap.so
account sufficient pam_unix.so
account required pam_ldap.so
Also, I would recommend running saslauthd as:
saslauthd -n0 -a pam
The -n0 tells saslauthd to fork a new process for each authentication
request. This prevents memory leaks in the pam libraries from accumulting
in saslauthd, although it does add some more overhead to the
authentication process. We haven't noticed any performance problems here.
I'm sure straight ldap (non-pam) is faster, but not enough to make a
difference for us.
