For joining a machine to domain, you must have a user with uid = 0.
But, begin with samba 3.0.11, the privileges can be used for use a other
user than root (uid = 0)
You can read more information in this pages :

The "root" user is only used for that, but after joining a domain,
changing the SID cause no problem.
Actually, on my network I not enabled privileges (in my test network :
yes and that work).
But, I use root user only for adding machine to domain, for the rest of
administration, I have
a administrator user with SID = S-1-5-21-xxxxxx-xxxx-xxxx-500 and
groupSID = S-1-5-21-xxxxxx-xxxxx-xxxxx-512
