Just to add: we moved from rc<something before 5> to rc15 recently, and
we now also see a lot of hangs with ldap_authbind.

The result handler for the initial ldap_search to find the dn to bind to
is never called. I assume Timo fscked something up recently in my
auth_bind code ;-P

Anyway, restarting ldap every hour or so with cron does the job :-|

I'd debug this if I had the time, but I won't have before next week.
