[squid-users] Squid3 reverse proxy ntlm authentication

I need to configure the Squid3 to authenticate via NTLM
reverse proxy authentication. I have instaled and configured
the squid but the browser requires the password again and
again.

Anyone have a clue to help me?

Here my configuration:

./configure --prefix=/usr/local/squid
--exec_prefix=/usr/local/squid --enable-ssl
--enable-auth-ntlm="ntlm,basic"
--enable-basic-auth-helpers="winbind"
--enable-ntlm-auth-helpers="winbind"
--enable-external-aclhelpers="winbind_group,wbinfo_group"
--enable-delay-pools --enable-removal-policies
--enable-underscores --enable-cache-digests
--disable-ident-lookups --enable-truncate
--with-winbind-auth-challenge

squid.conf

### pure ntlm authentication
auth_param ntlm program /usr/lib/squid/ntlm_auth

### provide basic authentication via ldap for clients not
authenticated via kerberos/ntlm
