How to allow mech other than plain?

[Jim Worke]

Currently, I'm using cyrus-imapd-2.1.9 and cyrus-sasl-2.1.7.  I've installed 
cyrus-sasl-plain and cyrus-sasl-md5 RPM.  When I use plain text 
authentication, it goes to saslauthd to PAM.  But when I set the client to 
use CRAM-MD5, the log shows that it's looking for /etc/sasldb2.  Since I'm 
using PAM, I'm not using /etc/sasldb2.

Anyone can help me?  Maybe point me to some documentation on this...
