What does this virtual server do / when is it called?

Do you call the linelog or detail modules in any of its sections?

You need to look at the debug output. On ubuntu run it as
"freeradius -X" and examine the output then authenticate something
you expect to get logs for.

Mostly not useful - you really want linelog or detail, not the
main server logging.

Check -X debug output.

Send the debug here if it doesn't make sense, though it's fairly
straightforward to read (if verbose). Right from the FreeRADIUS
banner at the top and including an authentication packet.

A small suspicion is that you might need to put logging in
pre/post-proxy sections if you're trying to log non-local auths.
