I wish there was. There are some helpful Sun engineers in sustaining
engineering, but Sun's relationship to Samba has gotten very frosty
since they crammed their Procom-bought CIFS server into the OpenSolaris
It's a shame, Solaris used to be one of our major platforms and
could be again if they decided to help third-party developers instead
of hindering them with non-third-party available API's etc. Yeah
we could just look in the kernel code but they should be making
this stuff available in a stable, supported fashion.
Oh well, maybe when Oracle cans the Solaris in-kernel server as a nasty
security problem then they'll come around :-).
