[Samba] Domain Administrators Not Recognized in Samba3

Ok lemme get this straight.   You're saying that there needs to be a
samba account with posix uid of 0 in order to join the domain?  That
doesn't make sense.  If you're a domain admin, you're a domain admin. 
If this is the case, the samba team is forcing a huge security problem
upon us as all domain admins would now need to have a posix id of
0....making them all effectively root.  While domain admins are only
superusers to samba, giving them all uid 0 would make them superusers
globally.  Not the brightest of ideas.

If you're saying that I need to be root *locally* to join with a domain
admin account, then thats not an issue.  I'm doing that.

I ssh in as my normal user, run `sudo su -` to become full root, then
execute `net join -U travis DOMAIN`. 

If this seems ok I'm going to start digging around the source code I
