I run pppd direct on the tty via init. This allows my Windows 95 users to
login without a dialup script, the dialup script was the biggest cause of
user support problems. Windows 95 is still my biggest support problem!

I encountered the same problems as you with pppd only updating wtmp and not
utmp. I also wanted pppd to read the users .ppprc file. I am runnning
2.1-STABLE, so it should be the same as you.

You may have also noticed that pppd doesnt always update the wtmp file when 
a
user exits. I think when a process aborts abnormally init will clean up any
entries in utmp and wtmp, but only if there is an entry in utmp.

So as far as I can tell; the fact that pppd updates wtmp but not utmp can
really be classed as a bug.

I gave up waiting for someone else to fix it, as I'm not much of a Unix
programmer, and had a go myself. It was relatively easy to do, but Im not
sure whether I've done it in the best possible way. If you want I can send
you the diffs for the file upap.c in pppd source.

It now works great for me, I can now report users time logged correctly and
can do a 'who' and see who's logged in.

Im really not sure whether, or indeed how, to submit my changes to the
freebsd group, perhaps someone could help me.
