Well everything seems OK (aka it matches what I get on an Linux AD client)

I am sure this stems from the fact that I am unable to use "net ads join" to join my domain but instead I have to use "net rpc join". Even now after joining with "net rpc join" I seem to have problem with the RPC calls, but the ADS calls succeed.

I don't understand the error messages and google doesn't help and I see a long history on the list about this problem. Is there anybody can shed light on these particular failures:

Which is why I was suspecting kerberos.
Just how did you build samba4 ?, what packages did you install and where 
from ?
I installed openindiana in a VM, but that was just about as far as I 
got, probably need to do a bit more investigation, I couldn't get samba 
configure to find gcc, it is so much easier on Linux.
