Hi,
I have been doing some research on finding documentation on how to use 
PAM authentication with Hylafax. On hylafax website it only says in 
many places that  Hylafax 4.2 supports PAM, but no documentation on 
how to get this setup and working. I also downloaded the latest source 
to see if it comes with some documentation on this, without success.
From what ever information I could gather from googling, I understand 
that you have to create /et/pam.d/hylafax file with the usual pam 
entries. But I am at a loss to understand how to tell hylafax to use 
PAM instead of the default hosts.hfaxd file for user authentication.
In '/etc/hylafax/hfaxd.conf' I have found the following line - 
UserAcessFile:  "/etc/hosts.hfaxd". However this is commented out. Is 
this the place where I tell Hylafax to look for PAM authentication? if 
yes what is the directive? Do I have to install some additional 
modules? Is there any way to find if the installed Hylafax packege has 
PAM support?
I am running  hylafax-4.2.1 on RHEL 4.0.
