The mailing list for users of the eduroam Configuration Assistant Tool (CAT)

[Stefan Winter <address@concealed>]

Hello,

this is a recommendation we have on the eduroam wiki since a long time indeed:

https://wiki.geant.org/display/H2eduroam/EAP+Server+Certificate+considerations

(see the table, second entry)

And for the CAT property check, you mean, like the check that exists in CAT since several years?

https://github.com/GEANT/CAT/blob/release_2_0/core/diag/RADIUSTests.php#L261

Please run the CAT checks against the realm in question or let us know the realm so we can. If the check does not bark on this form of server name, we will need to check the code. The intention definitely is that you WILL be warned in these cases.

Greetings,

Stefan Winter

      Good $timezone,

Today I realised I had been a derp and set up a new eduroam service with a EAP Server Name along the lines of “CN=Organisation X eduroam Server”. All my testing was going fine up until I started using a real mobile device to try to use it configured via CAT… it just failed… iOS logged it as:

[eapttls_plugin.c:968] eapttls_verify_server(): server certificate not trusted status 1001 -9807

… even though rad_eap_test with, apparently, all the same pre-requisites on validation was fine.

Much gnashing of teeth later, I remembered someone had mentioned that some clients need the CN to be in FQDN format (and, possibly, for it to be actually valid). While I have nothing to cite for this, could a sanity check be added to the CAT admin sections to ensure that the "Name (CN) of Authentication Server” appears to be in the right format?

Thanks,
