I have seen on three different occasions where domain users are being removed from the master group after cycling services on the CS. This has happened on 11.16, 11.24, and 11.28 in different environments. Sometimes the users stay in the master group and other times it seems like the permissions wipe after a few minutes and they are out again. I checked the forums for this and didn’t see anything specifically mentioned about it. Before I opened a support ticket about it, I wanted to see what everyone here had to say about it.
Thanks!!
