Well, there you go, you and I are at opposite ends of the spectrum. I am 
strongly against giving 'Administrator' a 'uidNumber' because you are 
turning a special windows user into an ordinary Unix user.
I personally think that 'Administrator' should be mapped to the root 
user (user 0), if you want another windows user to do administration on 
a Unix machine, create one and give this user a 'uidNumber'. It may help 
if you go look in idmap.ldb and see what the devs have mapped 
'Administrator' to.
