Return User DN to Authenticate

When the Access Manager directory is the same as the directory configured for Active Directory, this option may be enabled. If enabled, this option allows the Active Directory authentication module instance to return the DN instead of the User ID, and no search is necessary. Normally, an authentication module instance returns only the User ID, and the authentication service searches for the user in the local Access Manager instance. If an external Active Directory is used, this option is typically not enabled.
