SECURITY FIXES:
Remove a stray 'unbecome_root()' in the ntdomain an auth failure case. Only allow trust accounts to request a challange in srv_netlogon_nt.c. Currently any user can be the 'machine' for the domain logon. MERGE for 2.2. Andrew Bartlett (This used to be commit 0242d0e17827b05d8cd270f675d2595fa67fd5b9)
