I just found another tip on the net by using setgid on ntlm_auth binary
and winbind directory. I will try this tomorow morning .. see below ??
chown -R root:winbind /var/lib/samba
find /var/lib/samba -type d -exec chmod 750 {} \;
find /var/lib/samba -type f -exec chmod 640 {} \;
chown root:winbind /usr/local/bin/ntlm_auth
chmod 2555 /usr/local/bin/ntlm_auth
chmod g+s /var/lib/samba/winbindd_privileged
I just tried it on my dev machine and seems to work ..
