Sorry for the late reply. Were you able to get this resolved ?.
The LDAPRealm in GlassFish takes the following properties :
search-filter - LDAP filter to use for searching for the user entry based on username given to iAS. The default value is "uid=%s" where %s is expanded to the username.
group-base-dn - The base DN to use for group searches. By default its value is the same as base-dn.
group-search-filter - The LDAP filter to use for searching group membership of a given user. The default value is "uniquemember=%d" where %d is expanded to the DN of the user found by the user search.
group-target - The attribute which value(s) are interpreted as group membership names of the user. Default value is "cn".
search-bind-dn - The dn of ldap user. optional and no default value.
search-bind-password - The password of search-bind-dn.optional and no default value.
So in your case you might be able to specify the search-filter or group-search-filter properties to get a different behaviour.
