Re: Problems Authenticating against OpenLDAP

Try with configuration parameter
conn_max_pending (number of connections waiting for processing thread)
conn_max_auth (same, but for authenticated)

If you are using anonymous auth then, by default you have
conn_max_pending=100. In your configuration I don't see need to increase
threads to 32?

Does your open ldap has PostgreSQL backend? :)
Try to increase open ldap log level - to get info about connection opening.
