[Samba] SMB 3.0 & W2003: cli_negprot: SMB signing is mandatory ...

[panukorpela at yahoo.co.uk]

Hi!

I'm trying to connect to a share on a Windows 2003 server with samba 
3.0.0. I have edited smb.conf as was instructed in chapter 7 of the 
Samba-HOWTO-Collection to include the following:

client use spnego = yes

When I try to connect to the server, I get the following error:

cli_negprot: SMB signing is mandatory and we have disabled it
2355: protocol negotiation failed
SMB connection failed

Any help would be GREATLY appreciated!
