We just upgraded from JIRA 4.1.2 to 5.0.2. We also upgrade Crowd from 2.0.7 to 2.4.1. We are noticing that some of our users are no longer able to move tickets through the workflow (i.e., cannot close) that used to be able to do so. We have the Admin Helper plugin working and it identifies that the user does not have permissions to close because they are either not in the "Requirements Manager" group or the "Project Manager" role. However, when looking at the user's groups, we notice that they are actually a member of the "Requirements Manager" group.
