If your clients are attempting to use either the DIGEST-MD5 or CRAM-MD5
mechanisms, then the bad news is that the plugins can't use the hashed
passwords in /etc/passwd or /etc/shadow to authenticate users because
they need the plaintext passwords to work properly.  If they're using
those mechanisms, then you'll need to set those up using 'saslpasswd2'.

But then, depending on the client software, they may well be using the
PLAIN or LOGIN mechanisms, in which case you'll want to follow Brian's
advice and double-check on the SELinux policy.

HTH,
