Adding users to a group

[Mylonas, Elli]

Sorry to post so soon on same problem, but I haven't solved it yet.

I would like to add users to my wiki who are registered as members of  
xwiki.org. The reason for this is to allow them to log in once, and  
then be able to edit all the wikis of which they are members, instead  
of remembering a new login for each wiki.

I am entering the users in the Group Object as xwiki:XWiki.loginName  
where the loginName is the user's login at xwiki.org.

I found the FAQ on creating a new group HowDoICreateNewGroups, and  
followed the instructions. I now have a new group, and have  
successfully added users to it.

Then I go to the Preferences page, and make a new rights rule that  
gives privileges to the new group. For ex. I select the group, select  
view/edit and Allow.

This doesn't work. The user cannot log  into the wiki.  I think the  
problem may be the syntax I am  using for the user name. Can someone  
give me the correct syntax?

Is there some other way to do this?

Finally, perhaps this isn't possible, and I should just make the  
users log into more than one wiki?
