My IT dept setup my new MacBook Pro with 2 accounts. One is a local account and the other is on the Active Directory server. Both have administrative privileges on the mac.
I've been using the AD account to setup apps while on the corporate network (wired and/or wi-fi). My standard 'shutdown' procedure is simply to close the lid. There's a setting that will prompt for password after 15 minutes, so I can close it, walk to a conference room, open it and start typing w/o password, whereas if I unplug and lock it in the desk drawer for the night, I'll need to type a password after flipping it open.
Today, for the first time, I opened it while NOT on the corporate network. Many miles away from it, infact. I had closed it while using my AD account, so I typed in those credentials--and was denied. I tried again, one careful keypress at a time, verified caps lock off, etc. and still I was told invalid username or password.
So I tried the local account credentials. Those also failed.
How do I get back into my Mac?
