[squid-users] problems squid_kerb_auth

Hello

I'm doing a test with squid using kerberos configured as follows squid
and kerberos

squid.conf
auth_param negotiate program /usr/lib/squid3/squid_kerb_auth -d
auth_param negotiate children 10
auth_param negotiate keep_alive on

acl auth proxy_auth REQUIRED

http_access allow auth
http_access deny all

krb4.conf
[libdefaults]
     default_realm = VIALACTEA.CORP
     krb4_config = /etc/krb.conf
     krb4_realms = /etc/krb.realms
     kdc_timesync = 1
     ccache_type = 4
     forwardable = true
     proxiable = true
     dns_lookup_realm = true
     dns_lookup_kdc = true
     v4_instance_resolve = false
     v4_name_convert = {
         host = {
             rcmd = host
             ftp = ftp
         }
         plain = {
             something = something-else
         }
     }
     fcc-mit-ticketflags = true
[realms]
     VIALACTEA.CORP = {
         kdc = 192.168.1.155
         admin_server = 192.168.1.155
     }
[domain_realm]
     .vialactea.corp = VIALACTEA.CORP
     vialactea.corp = VIALACTEA.CORP
[login]
     krb4_convert = true
     krb4_get_tickets = false

On the client pointed out the proxy address configured and the following
variables firefox with the domain name:
network.negotiate-auth.delegation-uris
network.negotiate-auth.trusted-uris

When trying to browse I get the following messages in the logs with
debugging enabled.

(length: 59).
2011/05/29 02:42:57| squid_kerb_auth: received type 1 NTLM token

Does anyone have any idea of the problem? At the station installed
Kerbtray and it shows the ticket

Regards.
