	Same configuration, with freeradius 2.2.0 but using radwho from 2.1.8 
works. Instead of revert patching the file, I have copied radwho command 
from previous folders, and it works without any problem.

	So it seems that the problem is that now -F options is mandatory 
instead of optional.

	If this was the only problem, it wouldn't be any problem, but I'm 
having the same problem with radzap:

/usr/bin/radzap -P 131833856 -u <user> -N <ip> localhost <secret>
radwho: No configuration information in radutmp section of radiusd.conf!

	This same configuration with previous versions of radius works without 
any problem.
