I'm not an expert on the Amber usecase, but I suppose it is possible to
have multiple user groups for a single usecase. It could be to have a
shared space of data hidden from each user group. It could be to author
access/privilledges to the portal or resources depending on the user group.

I would assume the mapping of user to usergroups would be many to one
mapping. Unlike user roles I don't think it is sensible to have users being
mapped to multiple groups (there is a whole area of security to consider
here).

(I do have to note that usergroup IMO is not a must concept for a science
gateway)
