Hi all,
I'm working on a replacement for a legacy linux mail server: courier
POP/IMAP, Postfix, OpenLDAP. One of the requirements of the new mail server is
to authenticate against our AD infrastructure (I'll still keep a userdb in
OpenLDAP). SSO is not required since most of the clients don't log into our
domain. The current system has about 1,000 concurrent users on it during the
day (almost all are IMAP users). Inbox size varies but is generally very high
1GB+.
I'm considering dovecot as a replacement for courier IMAP on the new
server mainly for performance reasons. Cyrus was also considered but I'd rather
work with maildir format inboxes.
I'm in the process of installing a "proof of concept" server with CentOS 5 and
dovecot-1.0-1.2.rc15.el5. the production system will most likely run on RHEL
Question:
What's the best way (most reliable/fastest) to authenticate dovecot to AD?
If someone is doing this in a production environment can you offer any hints on
configuration for performance or what to expect in general?
Thanks,
chrisj
