REALMS, saslauthd and Cyrus IMAPD

[Diego Rivera]

Hello again - sorry to self-reply.

My apologies to all - I've found how to do this using the mentioned
HowTo, the "autocreate mailbox" patch, the LDAP filter feature for the
saslauthd-LDAP module, and other assorted components.

Only one thing left now - creation of "home" directories for each user
for .forward / .vacation processing (or equivalent behavior not
requiring the home directory).

I'll be posting a HOWTO for those interested when I have the procedure
completely nailed down.

Thanks very much for your attention.

Best wishes
