I *think* it shows two. But the output might mean more to you.

I have not seen a lot of people trying it, that might be the reason.

What I have done, and will send you off-list (privacy) is:
1) start a tcpdump (tcpdump -A -i any -w
dump_all_port_389_and_1812.pcap port 389 or port 1812)
2) start radiusd (radiusd -X 2>&1 | tee radiusd.out)
3) do a radtest (~16:33:28) (radtest klutest password 1812
41P***********qcfu | tee radtest.out)
4) do a ldapsearch (ldapsearch -x -v -W -D 'cn=Directory Manager'  uid=klutest)
5) stop the tcpdump

I will send you the files. Thanks again.
