I am trying to configure squid. I want to authenticate users using PAM. Pam authenticates users locally i.e when I use pam_unix.so & when I use pam_radius.so it is able to authenticate users using radius. But when I try to authenticate users against NT server using auth required pam_smb_auth.so It is not able to authenticate. What might be the problem. Please suggest . Thanks in advance. regards, adharsh
