Tue Sep 18 13:26:05 UTC 2018

I already fixed the problem that caused NTLM authentication to work only.

Subject: [squid-users] Problem with kerb/ntlm authentication

Sorry for my bad english.

This is the scenario

I have ubuntu 18.04.01 (with las update) with squid 4.2-2, samba and winbind
4.7.6,  AD on Windows Server 2012 R2/2016 with the las update, Client with
windows 10 1709 with the las update, firefox 60.2.0esr, google chrome
61.0.3163.79, firefox quantum 62.0 and internet explorer

I using this guide
https://blog.it-kb.ru/2014/06/16/forward-proxy-squid-3-3-on-ubuntu-server-14
-04-lts-part-1-install-os-on-hyper-v-generation-2-vm/ (Only to where
kerberos and NTLM are configured)

I joined the proxy to the active directory

All the commands seem to work correctly

I run this command

klist

Default principal: HTTP//srv-squid-krb.mired.lan at MIRED.LAN

I run this command

kinit squidtest

I create a proxy.keytab in my windows server 2012 r2 with this command 

ktpass -princ HTTP/srv-squid-krb.mired.lan at MIRED.LAN
<mailto:HTTP/srv-squid-krb.mired.lan at MIRED.LAN>   -mapuser MIRED\squidtest

        default_realm = MIRED.LAN

        dns_lookup_kdc = yes

        dns_lookup_kdc = no

        ticket_lifetime = 24h

        default_keytab_name = /etc/squid/proxy.keytab

[realms]

        MIRED.LAN = {

                    kdc = srv-dc.mired.lan

                    admin_server = srv-dc.mired.lan

                    default_domain = mired.lan

}

[domain_relam]

        mired.lan = MIRED.LAN

       .mired.lan = MIRED.LAN

I run this command

I run this command

I run this command

/usr/lib/squid/negotiate_kerberos_auth_test srv-squid-krb.mired.lan

The squid.conf its basic configuration only with

auth_param ntlm children 10

auth_param ntlm keep_alive off

acl red src 192.168.0.0/24

acl auth proxy_auth REQUIRED

and 

http_access allow red auth

But the problem is that Kerberos dont work. Only NTLM.

The question is, that only NTLM works, I've tried with Internet Explorer,
Google Chrome and Firefox. The other thing is that he never asks for
username and password, he uses the user credentials that he initiates
session to work (I do not know if this is the correct operation).

What could be happening?

                Sorry for the long email.
