[squid-users] Problem with basic auth ldap

Hello.

I'm having a problem with my squid, the basic auth ldap not working with
M$ Windows 7 clients, the message in the log cache is:

basic_ldap_auth.cc(685): pid=6936 :user filter 'sAMAccountName=none',
searchbase 'dc=example,dc=com'
basic_ldap_auth.cc(707): pid=6936 :Ldap search returned nothing

My squid.conf:

auth_param negotiate program /usr/lib/squid3/negotiate_kerberos_auth -s
HTTP/squidproxy.example.com
auth_param negotiate children 25
auth_param negotiate keep_alive on
auth_param basic program /usr/lib/squid3/basic_ldap_auth -d -v 3 -R -b
"dc=example,dc=com" -D "cn=Administrator,cn=Users,dc=example,dc=com" -w
"secret" -f sAMAccountName=%s -h domaincontroller.example.com
auth_param basic children 5
auth_param basic utf8 on
auth_param basic realm Internet control

Domain controller = Windows 2003 server R2 Standard
Squid proxy = Debian Wheezy
Squid Version = 3.3.8-1

I think the problem is with this version of Squid, because the version
3.1.20-2.2 works fine (test environment).

Thanks for the help.
