That was indeed spot on. The shared secret between RADIUS client and
server was too long. ~ 80 chars of random text is too long.

I've not thought out exactly where this occurs, and who is to blame,
but at first sight it looks like it is FreeRadius with its limit of 31
chars is the culprit:

"FreeRADIUS is limited to 31 characters for the shared secret."


Thanks all for your attention and especially to Olle who stopped by in
person and helped me think. I think he has a patch too; this was hard to
find, since auth_radius module hides the response from radiusclient-ng;
one small adjustment brings the fault code to attention.
