[squid-users] Kerberos Heimdal Server Authentication

[Panagiotis Bariamis]

Hello my setup is as follows :
Freebsd 11 Heimdal Kerberos Server and DNS properly configured (testlab
enviroment for example.com domain)
Freebsd 11 squid proxy server
Windows Client


I have created a keytab from the Kerberos Server for http/squid.example.com
Proxy server machine has no problem kinit ing with the keytab file and gets
a ticket

# klist
Credentials cache: FILE:/tmp/krb5cc_0
        Principal: http/squid.example.com at EXAMPLE.COM

  Issued                Expires               Principal
May  9 15:38:36 2018  May 10 01:38:37 2018  krbtgt/EXAMPLE.COM at EXAMPLE.COM

My squid.conf is as follows concerning the authentication :
auth_param negotiate program
/usr/local/libexec/squid/negotiate_kerberos_auth
auth_param negotiate children 10 startup=1
auth_param negotiate keep_alive on

Trying to use :
 # /usr/local/libexec/squid/negotiate_kerberos_auth_test squid.example.com
| awk '{sub(/Token:/,"YR"); print $0}END{print "QQ"}'
| /usr/local/libexec/squid/negotiate_kerberos_auth -r -s http/
squid.example.com

fails with :
| negotiate_kerberos_auth_test: gss_init_sec_context() failed:  An
unsupported mechanism was requested. unknown mech-code 0 for mech unknown
BH gss_accept_sec_context() failed:  A token was invalid. unknown mech-code
0 for mech unknown
BH quit command


Any ideas ?

Thank you ,
