[Samba] Trouble adding machine accounts

[jeff sacksteder]

I'm not able to add machine account(specifically Samba member servers)
to my Samba 3.0 Domain. When I try to run 'net rpc join' and provide
the root credentials, I get 'NT_STATUS_NO_SUCH_USER' in the output. My
domain database is in LDAP and root is a local unix user. I know auth
works, because 'net rpc info' works. It seems there's a problem
mapping between the domain admin SID and the root user. I tried the
instructions on this page -
http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/rights.html#id2609879
and while they produce no errors, they don't resolve the problem.

I've been fighting with this for some time and it's likely I have made
some sort of error in the directory or the associated files. I'm not
sure how to go about troubleshooting this next, though - where to
begin?
