I got an interesting error the other day at a client’s site. They installed Release Management Update 2013 update 2 RC. When they tried to open the release management client, they got the error:
User xxxxxxxx does not have access to the release management server. Please contact your administrator.
What was weird was the user clearly had access. After digging through the logs, we realized that the Release Management client he was using was Release Managememt update 1. After upgrading him to the same version (Update 2 RC), everything worked as expected.
