[Samba] Net ads join

[Tom Skeren]

O.K.  well no one has responded to any requests for help yet.  Maybe 
I'll get lucky this time. 

Switched to the Red Hat web server.  Configured 3.0.3 --with-ads.  Do 
net ads testjoin, system response:

LINUX@'s password:  (type pass) (response)
[2004/05/07 09:49:11, 0]  libads/kerberos.c:ads_kinit_password (135)
    kerberos_kinit_password LINUX$@ failed:  Malformed representation of 
principal
Join to domain is not valid.

What have I got wrong?  Any suggestions would be appreciated.
