RadZap

[Radius]

When I run radwho -r to get all the information of a login.

I need to clean this one out of the list.

I get all this below and have tried several commands but it keeps returning 
me to this
with no real reason why it didn't work.

Usage: radzap [options] server[:port] secret
       -d raddb_directory: directory where radiusd.conf is located
       -N nas_ip_address: IP address of the NAS to zap.
       -P nas_port: NAS port that the user is logged into.
       -u username: Name of user to zap (case insensitive).
       -U username: like -u, but case-sensitive.
       -x : more debugging output

I have in the radius.conf to remove stale connections, but they seem to 
always remain
and these peopel are not conencted.

Thanks
