1xMaster / 1xBackup environment. Chrome Browser on Windows 7.

Login to http://master/umc -> single sign-on on backup (visible on ucs-sso.)
Switch to backup from UMC dropdown on master
Logout on Backup -> redirect to master and backup (for logout)
Enter http://master/umc in browser -> Get a valid UMC Session!

Then when trying to logout on master:
