Were it that simple. Your sqn Ad must complete the ASR with the users PUID.
Which takes about 30 seconds. Then you send the new ASR to Atlas and they will add you to the new unit. The problem with the way you are doing it is expecting the AD to sort it out. One of the Squadron aircrew must be the IT security Officer...or the LSO....they can do it very quickly. On my last Squadron the Ops Officer was the LSO / ITSO and he did it all for the entire Squadron.
