Authentication Squid by Active directory

[emmatshahwa]

Hello,

I installed squid on a Centos7 virtual machine.
I opted for Active Directory authentication in 2012 based on the link https://access.redhat.com/documentation ... entication.
On clients machines, this proxy is configured in the browser for Internet access. I have no proof that authentication is done via AD. I tried to take an off-domain machine to test. I notice that the Internet is granted to him. Yet my wish was to give access only to those who are in the domaine with credentials.

I do not know where it's blocking.

Can someone help me ?
