Subject: Authentication problems since Redhat 5.5 updates

We had a nice trouble free cyrus running until it was updated
with updates from Redhat today.

I've tested with testsaslauthd (no service name given) and it works OK,
so I'd think things are fine on the pam, AD and ldap end.

In the cyrus server's maillog I'm seeing messages like this
from attempts to connect from the remote webmail:

Jul  2 13:54:22 navi imap[4073]: badlogin: webmail.example.com [XXX.YYY.ZZZ.111] CRAM-MD5 [SASL(-13): user not found: no secret in database]

Logins from some other IMAP, like my thunderbird, using a secure IMAP port, work OK.

cyradm can connect, but scripts we have, using IMAP::Admin have stopped working.

# cyrsetquota dteed 100
IMAP::Admin [ initialize ]: try NO Login failed: authentication failure

This is cyrus 2.3.7 from Redhat, identifying as:

These packages were updated by Redhat related to sasl:

Jul 02 10:36:41 Updated: cyrus-sasl-lib-2.1.22-5.el5_4.3.i386
Jul 02 10:37:11 Updated: cyrus-sasl-plain-2.1.22-5.el5_4.3.i386
Jul 02 10:37:44 Installed: cyrus-sasl-md5-2.1.22-5.el5_4.3.i386
Jul 02 10:38:01 Updated: cyrus-sasl-2.1.22-5.el5_4.3.i386

I tried removing cyrus-sasl-md5 and restarting saslauthd but it did not help.

There has to be something silly getting in the way but what?

I have things working again.  I had disabled Unix authentication in pam
temporarily to try troubleshooting with my account.  That had the side effect
of disabling the cyrus user from authentication.  So that explains the
scripts using IMAP::Admin breaking.

I also removed the package cyrus-sasl-md5 and I believe this has
an impact on the issue I was facing with "CRAM-MD5".

Any tips on how to co-exist with that package are welcomed.
