Redhat users will need something similar to:

 nntpcache   auth       required     pam_unix_auth.so
 nntpcache   account    required     pam_unix_acct.so

in their /etc/pam.conf file.

Debian users require something similar to

 auth     required       pam_unix.so
 account  required       pam_unix.so
 password required       pam_unix.so
 session  required       pam_unix.so

in their /etc/pam.d/nntpcache file (or whatever you've set it to in the nntpcache config file). Since the Debian PAM authentication modules require the requesting application to be root/in group shadow, you have three choices:
	* tell nntpcache to run as root ("user root" in nntpcache.config), 
	* use the suid pipe authenticator. i.e
                  auth=user/passwd;pipe
	  with default pipe authenticator, "unixauth". See "pipeProgram" in
	  nntpcache.config, for more details.
	* not use shadowing, and build your own PAM authentication modules
