Given that's what Samba returns, I would knock it up as an error in the
spec.  I've CC'ed Steve French, so see if he knows how to get such
errata into the next version.

For detailed protocol questions, I would suggest joining the developers
list - samba-technical at samba.org, and the developers IRC channel
#samba-technical on irc.freenode.net.  (NOTE to other list-members: 
These are for technical discussions of Samba internals, and is not a
help channel)
