You are (or were) mapping Administrator to root, you had in smb.conf
username map = /etc/samba/user.map
which should contain one line:
!root = OURDOMAIN\Administrator
This would, when Administrator connects via Samba have mapped the
Windows user 'Administrator' to the Unix user 'root'
However, due to a recent change, any RID under '1000' is ignored unless
you also set 'min uid = 0' in smb.conf
If you run 'getent passwd Administrator' on a Unix machine, you should
get something like this:
This is using the 'rid' idmap backend.
As you can see, Unix knows 'Administrator by the ID '10500'. '10500' !=
'0' ('0' being the Unix ID for 'root')
Do not do anything directly on Unix as Administrator, If you want to use
Administrator on Unix, use the 'root' user instead.
I hope this helps.
