Subject: [exim] Exim and Active Directory
Hi:

I have been running an Exim/Courier-Imap system for campus email for
several years. We recently introduced MS Exchange 2003 for faculty and
staff, leaving the students on the Exim 4.52 system. The Exim/Courier
system uses SUN's iPlanet LDAP for authentication and Exchange of course
uses Active Directory. Both systems use the same '@uleth.ca' local
domain, so there is a fair bit of manual routing required to get mail
delivered to the right system, and both directories have to be in sync
or I can get mail looping. To reduce the complexity a bit, I would like
to run both systems from the same directory. Getting Exim to run with
Active Directory seems more feasible than the alternative.

Is anyone successfully running Exim/Courier-Imap using Active Directory
for authentication and LDAP lookups? I notice that Active Directory is
NOT one of the options for the config variable LDAP_LIB_TYP, so which
type works best? Any problems with it? Also, did you have to modify
the Active Directory schema to support the needed attributes or did you
find appropriate predefined ones? I can't find anything to use for
mailQuota but maybe I haven't looked hard enough. Any comments or
references greatly appreciated. Thanks.

Russ
