[Samba] Cross realm trust status

[Boris Lechner]

Hi,

I'd like to set up a Samba PDC trusting a Heimdal Kerberos server for 
user authentification and web SSO, but doesn't found any recent 
information about this subject.
Could someone please tell me what's the current status of this kind of 
trust ?

If it's still incomplete, is there a way I can help/test on this point, 
considering that I don't know anything about the Samba internals ?

Best regards,
Boris
