net ads join <-> cross realm trust

[miguelsanders at telenet.be]

Dear all

At our site we have cross realm trust between AD and UNIX, where the user accounts are located in AD and the service principals in UNIX.
Now it seems that net ads join creates computer account in AD along with a host principal (host/FQDN at AD) and a cifs service principal (cifs/FQDN at AD).
Because of the trust, wouldn't it be possible to create those service principals in the UNIX realm (where they actually belong).
