e-Campus Errors when moving between services

We've noticed a slew of errors happening when users go from one service (like the Tackboard) to another (Student Employment).  Somehow the users' logins have been corrupted.

While it is our intent to move away from the current login method ~ that process will take considerable time, we have instituted a temporary "fix" which clears the previous service's session data when a user navigates to another service.  Because the user is still logged into ecampus, should the user return to the original service, the session will be recreated and user experience should not be adversely affected.
