Having problems here also. I cant connect to iDisk. I go into .Mac preferences and set my username and password, with which I can log in from the net and used with 10.2.8, I check my iDisk settings and everythign goes fine. i flip back to .Mac settings and the password setting is no longer correct (different # of characters) i flip over to iDisk tab and get told i have wrong username and password. Backup reports the same error; wrong username/password. Kind of ironic that Apple's new operating system doesnt talk to its own overpriced pay service. HMMMMMM.
