Sun Java System Federation Manager 7.0 User's Guide

Return User DN to Authenticate

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