[Samba] Samba4 and Squid3 with ntlm_auth

[ivanmartinezz at cantv.net]

Hello there.

I'm try to configure squid3 with samba4-alpha-10 autentication.

My samba4 pdc work fine with a simple smb.conf:  

[globals]
        netbios name    = PANTRO
        workgroup       = MYDOMAIN
        realm           = MYDOMAIN.LAN
        server role     = domain controller

[netlogon]
        path = /usr/local/samba/var/locks/sysvol/mydomain.lan/scripts
        read only = no

[sysvol]
        path = /usr/local/samba/var/locks/sysvol
        read only = no

[compartido]
        path = /home/compartido
        read only = no

## End of file

My squid.conf file is simple too:

visible_hostname pantro.mydomain.lan
cache_mgr myemail at mydomain.com.ve
http_port 3128
cache_mem 128 MB
cache_dir ufs /var/spool/squid3 200 16 256
access_log /var/log/squid3/access.log squid

# Configuración de proxy detras de un proxy
cache_peer 192.168.3.10         parent    3128  3130  proxy-only default

## End of file

With this configurations files the IE8 (in windows) and FireFox (in linux)
show me the auth box but my user can't loggin success.

I'm try with "administrator" username, "administrator at mydomain" username
and "administrator at mydomain.lan" username.

I don't know, maybe a compilation option missing.

Exist a how to for this?
