Using LDAP groups - No users are listed in subwikis Global groups

Hi,

I have several LDAP groups to control access to pages over a handful of wikis. Giving permissions to this groups on the main wiki works perfect.

When I look into the Global groups xwiki tells me that there are no users in this groups. When list the users on the main wiki all users are there.

Must I assign groups to subwikis ?

Ciao

It looks like that the user count contained in a group is always displayed as a -.That does not mean that there is no user in this group.
My assumption was that the global groups have no effect in the subwiki but this not correct. The groups works as expected.

In my opinion it should be an improvement if the user count is displayed in the subwiki.
