Could you please provide some ideas on how to add this functionality to gerrit? Maybe a special "Group Managers" group that has admin permission over other groups? Is this even something that upstream Gerrit would be interested in or would it be better as a plugin?
I tried the service user plugin. It seems exactly what we need because all of our third party accounts are basically non-interactive user accounts. The only problem I'm having now is that I would like to use this with Gerrit 2.8.x but plugin (master) doesn't build against Gerrit 2.8.x :( Anybody know whether this can be easily back ported to 2.8?
