+        </list>
+        In this case, when PDS is performing access check, it normally does NOT see user U being member of group DLG (because membership in Domain Local groups is not propagated to other domains in forest), and because of that, it replies with AccessDenied error. Setting this parameter to true makes PDS to perform direct lookup for local group membership of user in his home domain to make sure that complete membership is evaluated. 
+        This additional lookup consumes PDS service resources and requires direct connection between PDS and domain controller of user's domain, so delegation using domain Local groups in multi-forest domains should be avoided.
