My ldap have subtree like this
The question is: how to configure alfresco to use a dynamic cn. The documentation contain a information about the "ldap.authentication.userNameFormat" and said "If set to an empty string (the default for the ldap subsystem), an LDAP query involving ldap.synchronization.personQuery and ldap.synchronization.userIdAttributeName will be performed to resolve the DN from the user ID dynamically. This allows directories to be structured and does not require the user ID to appear in the DN."
So I think the Alfresco will perform the personQuery but doesn't work too.
