ntlm_auth --helper-protocol=gss-spnego

[Henrik Nordstrom]

In what ways does the gss-spnego helper protocol differ from the 
squid-2.5-ntlmssp protocol besides using SPNEGO blobs instead of NTLMSSP 
blobs?

Further, am I correct in that this mode implements the NEGOTIATE SSP blobs
including buth NTLM and Kerberos, or is it just the Kerberos side of
things?

The reason to this question is that I am toying with the idea to add 
NEGOTIATE/SPNEGO support to Squid.
