I need some advice with an error i am getting when trying to start Squid which has integrated NTLM / AD auth setup.
heres the back story:
I've followed this guide word for word on the setup, installation and config of the server. So far everything has gone smoothly and i feel like i'm minutes away from getting this system running.
I am able to-do
Wbinfo -a administrator kinit Administrator klist
each command gives a confirmation that it ran successfully and worked as expected.
The Linux box has successfully joined my domain and i can do AD lookup's on users and groups.
however when i attempt to startup the squid service i get the following from the CLI.
[root@squid ~]# service squid start Starting squid: . [ OK ]
But then get connection errors from my browser saying the proxy refused the connection, further investigation inside the /var/log/squid/cache.log for squid shows the following error.
