[squid-users] Squid and Kerberos problems

[Olivier CALVANO]

Hi

I request your help because i want use NTLM/Kerberos for authenticate my
user.

For NTLM, i use Winbind, no problems,

[root at gw]# wbinfo -t
checking the trust secret for domain MYADDOMAIN via RPC calls succeeded

but for Kerberos, i can't create the .keytab


[root at gw]# kinit MYUSERNAME
Password for MYUSERNAME at MYADDOMAIN.FR:

[root at gw]# klist
Ticket cache: KEYRING:persistent:0:0
Default principal: MYUSERNAME at MYADDOMAIN.FR

Valid starting       Expires              Service principal
02/05/2015 04:51:25  02/05/2015 14:51:25  krbtgt/MYADDOMAIN.FR at MYADDOMAIN.FR
        renew until 09/05/2015 04:51:07

MYUSERNAME is the same account that i join the domain (net join) with
winbind


after, i put:

msktutil -c -b "CN=COMPUTERS" -s HTTP/gw.srv1-v4.tcy.myinternetdomain.org
-k /etc/squid/PROXY.keytab --computer-name OPHTCYSRV1V4-K --upn HTTP/
gw.srv1-v4.tcy.myinternetdomain.org --server adserver1 --verbose

and i have a error:

[root at gw etc]# msktutil -c -b "CN=COMPUTERS" -s HTTP/
gw.srv1-v4.tcy.myinternetdomain.org -k /etc/squid/PROXY.keytab
--computer-name OPHTCYSRV1V4-K --upn HTTP/

same error if i change gw.srv1-v4.tcy.myinternetdomain.org to
ophtcysrv1v4.myaddomain.fr
