Get client name with unlang

[Rahman DURAN]

Hi,

https://wiki.freeradius.org/config/run_time_variables here it says I can
use the "%C" variable to get clientname (clients.conf) but it also says
"The following variables are obsolete and have been removed from version 3
of the server. They are duplicates of the previous general cases, and were
only provided for backwards compatibility."

So how can I get the client name?  Blindly tried xlat %{client:name} but it
did not work.
