SMB signing.

Hi all,

	Is anyone using Windows SMB signing in a production environment ?
This is the signing proceedure created by setting the Registry keys
EnableSecuritySignature:1, RequireSecuritySignature: 1 in the lanmanserver
and lanmanworkstation parameters.

I'm playing with implementing this in Samba for 3.0, but am finding
that it doesn't seem to work when mixing Windows NT or Windows 2000 clients
with Windows XP servers. The clients get ACCESS_DENIED messages from
the servers and the signing verification seems to fail.

Of course it doesn't match the published spec, but that's just to be
expected I guess :-) :-).

I'd appreciate any data points from people actually running with this
turned on.
