I updated my developer beta to version 5 this morning on my work computer, and found it no longer accepted my password. I had to do a full restore (3 hours) from time capsule and download mavericks all over again to try again. Though this time I created a second admin account without a password also. So I've just reinstalled beta 5 and once again I can no longer log in. The little bubble pops up saying network login unavailable (this isn't usually an issue), but if I try either of the admin accounts (one with and one without password) it simply fails as though I've entered the wrong details. Anyone else had a similar experience? I'm on a Windows server domain, but the Mac always logs in whether the network is connected or not. Any suggestions before I restore again via Time Capsule and skip this update?
