[Samba] joining a domain without having Windows admin privileges

[J Raynor]

I would like to use "security = domain" for a samba server, but the only 
way I've found to do that is to issue the command "net rpc join -U 
admin%password" where "admin" is a Windows user that has the authority 
to create machine accounts.  I don't have that authority, and I don't 
think I can get it.

Is there another way to do this?  For instance, if the Windows admins 
add the machine account for me, can I issue a different command to join 
the domain?  What command?

I'm using samba 3.0.11.
