Unable to login @ login window with Active Directory User

I successfully bound my test machine to Active Directory and can search using dscl and id. I can also su to my active directory user account an authenticate perfectly. All search bases are correct and everything else looks fine.

When I attempt to login from the login window as an AD user, the window shakes. Clicking under Mac OS X shows that "Network Accounts Available". Looks like the CLI tool "dirt" is now gone as well, although insecure it would possibly show something here.

Anyone else having issues after binding to AD? I bound using the Directory Utility gui... I have not tried using my leopard bind script yet.

Thanks,
Ken
