HI Marcio,
The helper need a Kerberos token as input. Please have a look at test_negotiate_auth.sh which is in src/auth/negotiate/kerberos of the trunk version. The squid hostname must match the entry in your keytab and you must have done kinit to authenticate against a Kerberos server (e.g. AD) as user first.
Regards
Markus

I have trouble to authenticate Squid3 with kerberos in Samba4 domain. I'm using CentOS 7 and Squid 3.3.8 (yum install squid)
When I type the bellow command in terminal:
/usr/lib64/squid/negotiate_kerberos_auth -d -i -s HTTP/proxy.cms.ensino.br at CMS.ENSINO.BR
john xyz at 12345
I have the following error:
negotiate_kerberos_auth.cc(315): pid=6364 :2016/08/27 10:44:33| negotiate_kerberos_auth: DEBUG: Got 'john xyz at 12345' from squid (length: 14).
negotiate_kerberos_auth.cc(362): pid=6364 :2016/08/27 10:44:33| negotiate_kerberos_auth: ERROR: Invalid request [john xyz at 12345]
BH invalid request
Here are my files configuration:
/etc/krb5.conf
[libdefaults]
default_realm = CMS.ENSINO.BR
[realms]
CMS.ENSINO.BR = {
kdc = dc1.cms.ensino.br:88
admin_server = dc1.cms.ensino.br
default_domain = CMS.ENSINO.BR
}
[domain_realm]
.cms.ensino.br = CMS.ENSINO.BR
cms.ensino.br = CMS.ENSINO.BR
Keytab name: FILE:/etc/krb5.keytab
