Hi Stefan,

I tried again with Android EduroamCAT app but the auth. fail again:

Fri Jun 26 11:59:51 2015 : Auth: Login incorrect (TLS Alert read:fatal:unknown CA): [michele.devarda AT unimi.it] (from client IAM4 port 109 cli b4:30:52:28:38:d2)
Fri Jun 26 12:00:32 2015 : Auth: Login incorrect (TLS Alert read:fatal:unknown CA): [michele.devarda AT unimi.it] (from client IAM4 port 109 cli b4:30:52:28:38:d2)

The only way for authenticating with Android is configuring manually the Wi-Fi network with PEAP, MSCHAPv2 and without certificate.
In the EduroamCAT debug window I see only the root certificate with CN=VeriSign Class 3 Public Primary Certification Authority - G5
Is it possible that Android needs to install also the intermediate cert?  The Intermediate cert is present in our CAT config.

Thanks a lot,

Michele

Hello,

I have just tested your realm against the Verisign root and everything
works just fine.

There is not a single warning or error in the realm checks.

Could you verify if you still have an issue?

Greetings,

Hi Gareth,
thank you for your answer.

In the Radius server we installed  both server certificate (in attach
our eap.conf file):

Also in the CAT configuration we put root certificate and chain file
(see attached screenshot). Initially in the cat conf we put only the
root certificate and it worked fine only with Windows and iOS, but
didn't work with MAC OS X, so we put the chain ca file./
//Do you have any suggestions/?

Thank you again,

Michele

Hi,

 

I have tested your eap-config and it looks like it parses OK, and
installs a Verisign CA Cert:

CERT Subject=CN=VeriSign Class 3 Public Primary Certification
Authority - G5, OU="(c) 2006 VeriSign, Inc. - For authorized use
only", OU=VeriSign Trust Network, O="VeriSign, Inc.", C=US

Is this the correct CA cert you have configured in your radius setup?

 

You have a certificate chain present, so you need to ensure your
radius server is sending the intermediates.

I think you can test this via cat.eduroam.org site using the realm check.

Can you test this please?

 

Thanks,

Gareth Ayres.

Today the Windows CAT download for Univ. degli Studi di Milano seems ok.

The configuration for Android is still not working: we tested
eduroamCAT app 1.0.16 only with 2 kitkat 4.4 devices and we obtain the
RADIUS  TLS error (unknown CA):
/Thu Jun 25 13:44:10 2015 : Auth: Login incorrect (TLS Alert
read:fatal:unknown CA): [//michele.devarda AT unimi.it/
<mailto:michele.devarda AT unimi.it>/] (from client IAM2 port 109 cli
b4:30:52:28:38:d2)/

The CA config. works fine with WIndows, Mac and iOS systems.
I attached an app screenshot, I don't know if is it possible copy and
past the complete WiFi Logs from EduroamCAT App.


Thank you for your support,

Michele de Varda

    Dear CAT developers,

    I'm the CAT admin for Univ. of Milan.
    Today I did some tests changing our CA chain because the CAT
    Android client doesn't work for our university, this is the RADIUS
    log:
    /Wed Jun 24 11:33:02 2015 : Auth: Login incorrect (TLS Alert
    read:fatal:unknown CA): [//michele.devarda AT unimi.it/
    <mailto:michele.devarda AT unimi.it>/]/

    Now we can not download Windows configuration, we receive this
    message:
    /"This is embarrassing. Generation of your installer failed.
    System admins have been notified. We will try to take care of the
    problem as soon as possible."/

    Can you help us?

    Thank you for your great job
