Admin rights over a group

I have created a group and assigned one of the users to be an Admin. I would like for this Admin to be able to log on and administrator their own group. Like add,change or delete users. They only need access to this and nothing else. How can I do this? It is like different departments.

There is no role based administration in Openfire. Every admin gets full power. Though Security Audit Viewer will show which admin has done what. If that helps. This log can’t be deleted. Also those checkboxes in groups really do nothing. Well, they set something in the database, but it doesnt give any power to that user. I was always asking to remove those useless checkboxes until some additional functionality will be added…
