Can you run squid_kerb_ldap with strace -f -F to see when the permission
deny happens ? Just write a script squid_kerb_ldap_sh
#/bin/sh
strace -f -F -o /tmp/strace.out.$$ squid_kerb_ldap $*
and change your config file to use that script.
/tmp/strace.out.xxx should show where the permission deny happens.

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
