Hai Rafeal, Yes, i agree, this is the other most simple way, but i suggest, you remove/change on this page: https://docs.diladele.com/administrator_guide_stable/active_directory/kerberos/keytab.html The generated Kerberos configuration file will usually look like: [libdefaults] default_realm = EXAMPLE.LAN default_tgs_enctypes = rc4-hmac des3-hmac-sha1 default_tkt_enctypes = rc4-hmac des3-hmac-sha1 These are really outdated. ;-) To ( just the default ) [libdefaults] default_realm = EXAMPLE.LAN dns_lookup_kdc = true dns_lookup_realm = false Keytabs and samba, read: https://wiki.samba.org/index.php/Generating_Keytabs https://wiki.samba.org/index.php/Keytab_Extraction Greetz, Louis > -----Oorspronkelijk bericht----- > Van: squid-users > [mailto:squid-users-bounces@xxxxxxxxxxxxxxxxxxxxx] Namens > Rafael Akchurin > Verzonden: maandag 17 februari 2020 11:06 > Aan: Rafael Silva Daniel; squid-users@xxxxxxxxxxxxxxxxxxxxx > Onderwerp: Re: please, can someone help me with > the negotiate kerberos? > > Hello Rafael, > > There is an easier option *without* joining the Squid machine > to the domain, > See tutorial at > https://docs.diladele.com/administrator_guide_stable/active_di > rectory/index.html (it also applies to vanilla Squid without > our UI - just you would need to do more manual steps). > > Raf > > -----Original Message----- > From: squid-users <squid-users-bounces@xxxxxxxxxxxxxxxxxxxxx> > On Behalf Of Rafael Silva Daniel > Sent: Saturday, 15 February 2020 21:08 > To: squid-users@xxxxxxxxxxxxxxxxxxxxx > Subject: please, can someone help me with the > negotiate kerberos? > > Helo! i think i did almost everything right, firstly i made > it in a test enviroment with debian stretch running squid 3.5 > and a windows server 2008 based domain controller, and it worked! > > but when i tried to deploy it in the production enviroment > running debian stretch, squid 3.5 and windows server 2012 as > the domain controller the authentication never works, the > file /var/log/squid/cache.log shows this: > > 2020/02/14 15:40:21 kid1| ERROR: Negotiate Authentication > validating user. > Result: {result=BH, notes={message: gss_acquire_cred() > failed: Unspecified GSS failure.
