Hi,

My users are no longer able to log on to foreign eduroam networks. When I
test user logon from the Realm Check option on the CAT administration site an
error concerning certificate revocation comes op:

The extension 'CRL Distribution Point' in the server certificate points to a
location where no DER-encoded CRL can be found. Some Operating Systems check
certificate validity by consulting the CRL and will fail to validate the
certificate. Checking server certificate validity against a CRL will not be
possible.

Strange, because the URL in the CRL Distribution Point section
(http://www.eg-gym.dk/cert/EspergaerdeGymnasiumAndHF-CA.crl) is up-to-date
and functional as far as I can test.

The Realm Check itself has always failed for our domain, but we have been
able to logon to other eduroam WiFi's nevertheless. I have no idea when it
stopped working (my users are not very communicative). At home everything
works fine for both guests and local users.

Any ideas?

Best Regards

Mikael Klintorp
