I am trying to get FreeRadius running on FreeBSD to handle WPA from an OpenWRT
box, but I found that FreeRadius would crash when a request was processed.
The strcmp's around lines 1630 and 1659 can be done on a NULL pointer (eg
mainconfig.do_lower_user) which causes a crash.
It is trivial to add a 'mainconfig.do_lower_user != NULL && ' (or similar) in
front of these strcmps.
