Hi,
it seems the content of the secret string is interpreted when it contains a "%"
:
when a client (or server) declaration contains
secret fht8CD%E7am
it is interpreted as
getgenericconfig: block client xxxx.yyyyy: secret = fht8CDçam
One can see "%E7" is translated as the "ç" character.
Result : clients and/or servers who use a secret containing substring "%hh" are
rejected !
I suspect the function unhex() in gconfig.c to be the culprit...

This case is mentioned in the manpage radsecproxy.conf(5):
If you want to write a % and not use this decoding, you may of course write % in hex;
i.e., %25.

Hi Fabian,
Sorry for not have seen that but we don't choose the secrets used : the
clients/servers administrators choose their secret which
are put in configuration files for FreeRadius (in production) and radsecproxy (for
evaluation). It's not expected to have to
translate the content of the secret string :-\.

Christian
