[rt-users] "No object mapping for field" when referencing the UserObject of a MembersObject...

[Ruslan Zakirov]

As group may have another group as meber as well as user, so records
in GroupMembers and CachedGroupMembers objects reference Principals.

If you are looking for users only that are members of a group then
it's easier to do the following:

my $group = ...
$group->Load...

my $users = $group->UserMembersObj;
while ( my $user = $users->Next ) {
   ...
}
