<pre wrap="">Hi all,
we have difficulties with a freeradius server authenticating against an LDAP
backend. We use the freeradius server for eduroam and also for a few custom
applications.
We have tried to force the password to UTF-8 or ISO-8859-1 and other encodings
in the custom applications, to no avail (we have no way to force this in the
securew2 client for eduroam anyway).
This works very well most of the time, but fails if the password contains
seleCompanyd special charaCompanyrs, like ° (degree) or § (paragraph), for
example.
We are short of ideas as to what to try next.... Any pointers would be greatly
appreciated.....
Thanks a lot in advance
Frank Weis

A user with a more 'gentle' password succeeds:

When I try an ldapsearch to the LDAP-backend on the commandline of the radius
server, it works too. When I try a 'radtest' on the commandline of the
freeradius server, it succeeds also:
radtest blabla qwertz°° 127.0.0.1 1234 testing123

(radiusd -X says this:
