I'm in the process of setting up another Confluence (ConfB). I validate users through my crowd-installation. I have users that need access to both the existing Confluence (ConfA) and ConfB - and more importantly, I have users (new-users) which will only be allowed on ConfB. They shouldn't even be able to login to ConfA.
I'm thinking about two solutions.
1) Create New-Users directly in ConfB. The old-users can gain access through integration with Crowd and new-users will have no rights on ConfA as they are not even i Crowd.
2) rename the "confluence-users" group in ConfB to ConfBUsers and give this group the global "Can Use" Put all the new users in Crowd and give them the group ConfBUsers. The old-users that need access I can also give the ConfBUsers group.
Are there any other (and better) solutions? Which solution will be the solution that is most "mainstream"?
