That's odd. The only thing writing the utmp file should be accounting
section. Did you perhaps forgot to restart the server after making the
change?

Anyway, from a quick glance at radwho, the relevant change is probably
https://github.com/FreeRADIUS/freeradius-server/commit/41960ed2 . If
you know how to reverese a patch and build from source, you can try
reverting the patch (direct patch link:
https://github.com/FreeRADIUS/freeradius-server/commit/41960ed2.diff)
and see if it helps. I'm assuming you have a non-empty utmp file
already? If it works, then you found a bug and pinpoint the source. If
it doesn't, then it's something else.
