IdP AuthN LDAP Connection Pooling + Directory with disabled anonymous binds...

Thanks for the reply!

This is what the directory responds with when a search without credentials occurs (this is from ldapsearch - code 48):

ldap_bind: Inappropriate authentication (48)
	additional info: Anonymous Simple Bind Disabled.

I'd like to use the pools as they were originally intended, so what are the options/config for returning the connections to the pool in a known state with BindPassivator?
