Worth considering first "Why should the user name be in the utmp file?"
The user isn't logged in to your machine; they are using a network
interface.
The mgetty FAQ has a section on this:

The reason it's pppd's job is that mgetty isn't doing the authorisation;
pppd is. Hence mgetty doesn't know who's coming in.
If you can't work all that out, and want a log of who's on, I suggest
you write a pair of scripts which log these details somewhere. The
scripts should be called /etc/ppp/auth-up and /etc/ppp/auth-down. The
pppd man page documents the parameters that pppd will pass to the
scripts. If you really really want to, you could use those scripts (I
guess there's no real reason why they have to be scripts, they could be
C programs if you prefer) to play with the utmp file (read +
*understand* "man utmp" before you do).
