[Users] Radius Authentication

[Edson]

The working SER installation uses radiusclient-ng 0.5.0-1. It was compiled
after a CVS download maded on the beginning on jun/2005. Unfortunatly I miss
the source code and am using an i686-RPM derived from that code.

I already try to use this RPM (version 0.5.0-1) on the Xeon machine. The
results are the same. Just same message on /var/log/messages:

"Mar  2 21:45:54 sip openser: rc_check_reply: received invalid reply digest
from RADIUS server"

When I start "openser -TDdd I see:
...

I double checked all the "dictionary" definitions, triple checked my OpenSER
and Radiusclient-NG config and were not able to find the mistake.

So I'm really out of ideas... Maybe is the return value ("Authenticated")
illegal?
