Web Proxy Filtering and Caching / Squid Proxy - SSO with Kerberos does not work
« on: November 10, 2024, 07:51:04 pm »
Hello everyone,
I have configured the Squid Proxy on OPNsense (latest version) and successfully connected OPNsense to the AD. When I access a website from a client, the login prompt appears, and I can successfully authenticate with the AD user.
After that, I installed the Kerberos plugin and enabled SSO for the proxy. When I enter the username and password of an AD user on the SSO page for testing, a token is generated, and it seems to be OK. At least when I deliberately enter incorrect data, I get a different message.
However, when I then try to access a website from the client, the login prompt still appears. But even when I enter the AD user’s credentials, I can’t get any further.
