Hello list.

I recently faced a strange issue while upgrading from openldap 2.3 to
2.4 (from centos 5.7 to 6.2, actually): the change was transparent for
every applications excepted Zimbra, for which any authentication
attempt was suffering from an unexplained 30s additional delay. Just
switching from explicit TLS usage on port 389 to explicit SSL usage on
port 636 was enough to fix the issue.

I would use ldapsearch -d -1 to see what function it was hanging in.
Unfortunatly (sort of), I can't reproduce the issue with any other client
as zimbra itself... ldapsearch works fine, even when run from the same
host as zimbra.

ldapsearch against the zimbra server works fine (no delay on closing)? Then that would imply the issue is with whatever client is making the connection to Zimbra. It looks like slapd is simply detecting the connection was never closed properly after about 30 seconds, and taking care of closing it. I don't specifically see any issue here. Initially I thought you were saying you were seeing this issue while initiating a connection, not while closing it.
