Are you using auth_bind=yes? That's been a bit broken. I finally today
did several fixes to it so that it won't hang at least with my stress
tests. The code is now in CVS and I built a new nightly snapshot if you
want to try before rc18 release.

Looks like ldap_bind() can't really be used while anything else is going
on. Now the code waits until all the existing LDAP searches are
finished, then it does the bind, and then nothing is done until the bind
is finished.
