Hi Rafal, if you wish I've a manual redacted in SPANISH for build a VM whit
Debian 10.5 running SQUID compiled from source, with kerberos and LDAP
authentication, plus AD groups authorizations.

I haven't had time to translate it into English yet.
Let me know if it works for you and I'll share it with you.

Best regards,
