The objectClass "User" is not defined in the proxy's schema?

p.



That's correct. But in translucent overlay's documentation, there is:
"Note: The Translucent Proxy overlay will disable schema checking in the local database, so that an entry consisting of overlay attributes need not adhere to the complete schema."
But it seems that schema checking is still in affect when doing searches. Is there a way to disable local schema checking altogether? Or do I have to build some dummy schema so that OpenLDAP is aware about objectClasses I want to search for?
What happens is that you use unknown schema items in the *filter*, which requires it to be known in order to apply appropriate matching rules and so. The schema relaxation in the documentation refers to enforcing adherence with allowed and required attributes of an objectclass, and with stored objectclasses complying with structural inheritance relationship. Schema items need to be known anyway.
