trouble using pam_auth for php auth

[deuce868]

I am trying to create a web system that checks existing linux user accounts for authentication. I have found the pam_auth module which I have installed and phpino() reports is there.

I then created a php file in pam.d with the following:

# /etc/pam.d/php
#

note: both an auth and account entry are required

auth sufficient /lib/security/pam_unix.so shadow nodelay
account sufficient /lib/security/pam_unix.so

I am getting an error of "Permission Denied" when I try to authenticate. This is with the correct username/pass. I tried to copy login to php and edit it as the instructions suggest, but that just gets me the error "Error in service module".

Any ideas as to what I need to do to get this authentication working? Anyone used pam_auth successfully? Are there any other alternatives?

Thanks!
