first use the token "--helper-protocol=squid-2.5-ntlmssp"

This is not a Squid issue but a permissions issue
Many problems cam from Squid did not have rights under the
/var/lib/samba/winbindd_privileged or /var/run/samba/winbindd_privileged

The ntlm helper try to access for read/right on the
/var/lib/samba/winbindd_privileged/pipe socket file
This directory is on 0750 permissions with root and winbindd_priv group.

The first step is to add the squid user under the winbindd_priv group eg
usermod -a -G winbindd_priv squid
second is to chmod 1777 /var/lib/samba/winbindd_privileged/pipe
Bu you will fight again and again.
So the best way is to turn the partition that store /var/lib/samba into acl
mode in order to perform a
setfacl -R -m u:squid:rwx /var/lib/samba
setfacl -R -m u:squid:rwx /var/lib/samba

And you will be able to authenticate correctly members....
