Exim, LDAP Delivery Crash
I've encountered a peculiar bug in either Exim or OpenLDAP, and request
advice on which to file a bug against.
Quick Explanation:
When delivering mail with more than one recipient, the first recipient
succeeds, but the second recipient causes the Exim delivery process to
crash with an OpenLDAP 'assertion failure' error.
Long and Dirty:
I use LDAP to look up several pieces of information when delivering
each email. This is a service provider set-up, and supports many
domains, therefore I look up such information as server which speaks
for the domain (e.g. mail.fubar.com -> virtualmail14.mycompany.com,)
actual delivery domain (e.g. fubar.com -> mail.fubar.com,) per domain
aliases, global aliases (spam, abuse,) and user account information.
This setup results in a half dozen lookups for each delivery. I
believe that the crash is caused by Exim's caching of LDAP connections
somehow. I know that all of the lookups are successful, because if I
run each recipient seperately, they all work. Also, the first works,
which means that the current LDAP connection works. But when the
second delivery goes to look up its last item (the user's userrec -
homedir, uid, gid) it pitches an error, crashing the Exim delivery
process.
The Question:
Exim or OpenLDAP? Whose bug?
Thanx for any advice,
Clint
