[Samba] net rpc join -U root error

[Adam Williams]

On my server, I have root in LDAP, and am following the Samba3 by 
example book, but I'm unable to get it to join the domain.  I'm running 
samba 3.0.25b.

[root at gomer samba]# net rpc join -U root%xxxxxxxx 
                            
Unable to find a suitable server

[root at gomer samba]# net rpc testjoin -S GOMER -U root%tical123
Join to 'ADMIN' is OK
[root at gomer samba]# net rpc testjoin -D DOMAIN -U root%tical123
Unable to find a suitable server
Join to domain 'ADMIN' is not valid


I google searched for the error, but didn't find a solution.  Any ideas?
