I hope so anyway :-)

I am not so sure anymore. I tried to use the squid_kerb_auth_test
utility, but it still gives me errors on the tokens (see below for
listings). I may add that I compiled both squid3.0 and squid_kerb_auth
1.0.5. I used squid_kerb_auth_test with both squid_kerb_auth from the
squid_kerb_auth1.0.5 package and the squid3.0 package. I get errors in
both cases (though not the same, but that may simply be that one is
older).

I am using a windows server 2003 R2 corporate with SP2, in case there
may be an issue with a SP or something.

Last thing I can think of is the way I created the keytab (but
kerberos seems to like it this way) :
ktpass -out squidproxy.krb5.keytab -pass Password1 -princ
HTTP/squidproxy.ad.simia.fr@xxxxxxxxxxx -mapuser host_squid -ptype
KRB5_NT_SRV_HST -crypto DES-CBC-MD5 (could have used RC4-HMAC, but I
had problems before when I put in place unix authentication on
AD/kerberos).

I did it this way ... :-/

Hope I can make it work also.


Thanks,
