Hi Ming,
This indicates that now your client got the ticket from AD, but it does
not match the entry in your keytab. Did you set the environment variable
KRB5_KTNAME correctly ? Can you do a klist -ekt <squid.keytab> and compare
the entries with the wireshark information of the encoded HTTP Negotiate
request ?
Does the name, encryption type and , key version number (kvno) match ?

Hi Markus,
I tried the same test on a Windows 2003 domain with XP clients. I was able
to get pass the SGT from DC to the XP. Now my problem is the following squid
error: Any suggestion how to debug further?
