Did everything according to this article site
Squid does not start

2018/11/28 16:07:18| /usr/local/etc/squid/squid.conf:90 unrecognized: '/usr/local/etc/squid/squid.keytab'

what could be wrong, did exactly as the article all tests passed, no errors but when connecting temnemenee keymap, a proxy just doesn't start.

It looks like you put /usr/local/etc/squid/squid.keytab on a separate line in the conf file.

That's actually part of the first directive just line wrapped in the box I believe. The first directive should be:
auth_param negotiate program /usr/local/libexec/squid/negotiate_kerberos_auth -d -k /usr/local/etc/squid/squid.keytab
All one line.

ahhh, I'm crying tearfully. I broke my whole head and it turns out that's it. Thank you it worked!
I will be glad if you still help! Not passes authorization on, that the strange over time.

But in the squid on the tab "Real Time" in table "Squid Cache Table"

Where he gets this date is "01.01.1970 03:00:00" is unknown, perhaps because of this, and does not pass authorization.

Hmm, interesting.

I have never tried that configuration nor do I have the infrastructure to test it. I just saw the error initially.

1.1.1970 is 0 seconds in epoch time so it looks like it's not getting a time stamp for that. Hard to say why that would be, I'm not sure I can help much with that.

@helpuser
copy your keytab file as: /etc/krb5.keytab
chown :proxy /etc/krb5.keytab
chmod 0750 /etc/krb5.keytab

squid.conf :
