Brett,
There was a PAM thread back in early December where we discussed this.
I posted a bunch of PAM testing combinations that did/didn't work. One
of which was trying to use system accounts through "system-auth" which
is really pam_unix.so. This method would not work for me in 7.3.1 no
matter what I tried. I also never found a solution.
Google has the full thread here

I had a look through some of the authentication source as well, but I
didn't know enough about it to figure out what the problem might be
specifically with pam_unix.so.
Probably not what you wanted to hear, but you aren't the only one.
