[squid-users] passwd file

I am trying to set up authentication on RH 7.1 with squid 2.2
(authenticate_program path/to/program path/to/passwdfile). The docs seem
pretty simple on this, but I am not sure what passwd file to use that is
ncsa complient. I was told /etc/passwd was not. Can someone send me a snip
on what things would look like in squid.conf for RH 7.1?
