ldap authentication multiple ou objects

Is there a way to do ldap authentication in pg_hba on a structure that
has multiple ou objects?

Lets say I have an ou=Users and then an ou per dept.

I want the ldap to do authentication no matter which ou the user is in.


My current ldap string is:

ldap://ldap.server.local/Users;uid=;,ou=Users,dc=server,dc=local

and it works if the user is only in the ou=Users but if he is in any sub
ou it gives authentication failed.


Thanks
