[squid-users] Question about changing authentication in a http session.

Sun, 02 Feb 2014 15:07:26 -0800 

Hi,
I am testing authenticating a XP machine with Kerberos, but the client tries Negotiate/NTLM first after which squid does not accept the change to Negotiate/Kerberos anymore. 


If you look at the wireshark log you authentication attempts at 20:44:20 for 
Negotiate/NTLM and at 22:44:30 the client changed to Negotiate/Kerberos, but 
the cache.log file does not get any request after the 20:44:20 NTLM request. 
I can only see the deny entries in the access.log.


 I use squid 3.4.1 from the repository from 24 Dec 2013.

Is this an expected behavious ?

Thank you
Markus
