Well, I've tried that and I still get a REJECT. I've attached the
output, one is for the startup output from 'radiusd -X', the
radius_debug_serveroutput.txt file is the output when I run radtest.
The only thing I've changed in the config files is to add the DEFAULT
Auth-Type = System at the top of the users file.
In the authorize section of sites-enabled/default Unix was commented
out, but I uncommented it. Everything else was as you list above.
Now that I think about it, I don't even NEED FreeRADIUS to use NIS,
since I'm running radiusd on the NIS master, the logins are all there
in /etc/passwd anyway. Well, that simplifies things a bunch. But it
still doesn't explain why I can't get any user to authenticate on that
server.
