Specifies the DN of the node where the search for a user would start. (For performance reasons, this DN should be as specific as possible.) The default value is the root of the directory tree. Any valid DN will be recognized. If OBJECT is selected in the Search Scope attribute, the DN should specify one level above the level in which the profile exists. Multiple entries must be prefixed by the local server name. The format is servername|search-dn. For multiple entries:
servername1|search-dn servername2|search-dn servername3|search-dn
If multiple users are found for the same search, authentication will fail.
