There's a change in the authentication process in the new environment. In CI-RHOS we have used only local authentication and most teams only used shared account to login to the environment. In PSI (Upshift) we switched to LDAP authentication, thus you use your Kerberos credentials to log in to the system. What we do during the initial setup is paring of the Rover group name with the particular project and then it's up to Rover group admins to manage people who should be able to access the resources in PSI. That's why we need the Rover group name from you.
When creating a Rover group please give it a different name than your LDAP group. Ambiguity could be a potential problem.
