Subject: Merge from appliance:

>Another hopeful fix for CR#1168.  Change the RPC used in querying
>domain users from QueryDispInfo to EnumDomainUsers.  Hopefully this
>will fix the random dropouts that keep occuring when listing large
>domains.
>
>My thought is that since QueryDispInfo is only used in the NT user
>manager it may have a bug with large domains.  A more commonly used
>RPC may not have such problems.
