So i decided to update my machine to 10.5.5 before I pushed this out to everyone. The main problem i've seen so far is with a failed login using a mobile account that is bound to active directory. My machine is currently bound to AD and i have a mobile account. When I start up the machine and attempt to login with my AD account, it fails. The only time the login works is when i unplug the machine from the network and log in. Everything in directory utility shows green light that i'm still bound to AD. At the login screen, I also have a green light saying network accounts are available as well. The only accounts that work are local accounts. Anyone else experiencing this and what have you done to cure it?
