Hi squid users,

i installed squid after this how-to guide:

http://serverfault.com/questions/66556/getting-squid-to-authenticate-with-kerberos-and-windows-2008-2003-7-xp/105857#105857
   (Getting Squid to authenticate with kerberos and Windows
2008/2003/7/XP)

Domain/Server Info:

Domain Name: homebase.local
Squid Server: squid 192.168.100.55
windows server 2008: srv-ads-001 192.168.100.130

DNS Name Resolution is working in both directions.

If i start the squid init script, squid tries to start, but i get the
following error message
in the cache.log :

After start the init script, i check the status immediately with htop,
and for a short moment,
htop show me the last 6 lines with:

(squid_kerb_auth) -d -s HTTP/squid.homebase.local

What do I have to make, to solve the problem?

Thanks for any ideas.

Bye,

Rainer
