What I would like to see is the following:
Now (using net ads join) I can see in kerbtray that a host and cifs service ticket are issued with the following form:
     host/FQDN at WINDOWSDOMAIN (in which FQDN is the fully qualified DNS name of the UNIX machine
    cifs/FQDN at WINDOWSDOMAIN

I would like to see that a host/FQDN at MIT and cifs/FQDN at MIT service ticket is issued by the cross realm since are UNIX principals are gathered in the MIT realm.

What steps need to be performed to obtain this?

Thnx a lot

  If you are joining the machine to AD, then the machine SPN
  belongs in AD.  If you want to put the machine as a principal
  in the Unix realm and map it to an account in AD, that is up
  to you.  But this is entirely different than joining the AD
  domain from my perspective.



  cheers, jerry
