pppd not logging user into utmp/wtmp

[Jeff Hill <jhill@hronline.com>]

Listing users logged in was working with the 'who' and 'last'
commands, but quit when I re-installed pppd/ppp-pam using the
same configuration files I previously had. 

With mgetty (which has been unchanged) I was using the
following login.config line:

	/AutoPPP/ -     -       /usr/sbin/pppd auth -chap +pap login

When that failed, I tried:

	/AutoPPP/ -    a_ppp   /usr/sbin/pppd auth -chap +pap login

However, this just lists all logins as a_ppp, not the user's
name. I'm not certain how utmp, wtmp, ppp, pam and mgetty work
together. I assume that it is pppd that is failing to log
users into either utmp or wtmp. 

>From the ppp.log below, it clearly shows the connection being
made on ttyS16 and the user's login name (maxxsign), but
that's obviously not getting logged into utmp or wtmp. 

I'm just lost at this stage. Any direction/suggestions
appreciated. 

Thank you,

Jeff Hill
