Update the doco on 'restrict anonymous' (note that 'guest ok' kills off the
benifit of RA=2), explain better what 'ntlm auth' and 'lanman auth' do, and
fix use spnego - all win2k clients use spnego.
Work on the client-side still needs to be done, but I realised that I need
to add a paramter to close off all plaintext authentication before documenting
'client lanman auth' will make any sense.
