I use Ubuntu in my Laptop. I also have a Nokia N8 phone. To connect N8 to "WPA2 Enterprise WiFi", I need to export some certificate from my laptop.

The page http://www.youtube.com/all_comments?v=B-2D1QR8C2c explains how to export the necessary certificate from Windows 7. Can you please explain how to export the certificate from Ubuntu?

Simply copying the file in /usr/share/ca-certificates/mozilla does not work.

Are you sure you installed a digital certificate on Ubuntu to access the wireless? Most people use a password rather than a certificate. If you did install a certificate, then you should be able to go back to where you installed it ( right click networking -> edit connection -> 802.1x security and see what file it points to for the CA certificate.

The certificate you want should be in /etc/ssl/certs. Try the command find /etc/ssl/certs -type d to see if you have any certificates there. –  BillThor Apr 12 '11 at 1:36

As Psusi pointed out, you can find the particular certificate that your laptop connection uses through the NetworkManager interface. Since using the certificate directly didn't work for you, I suspect that you may need to convert the certificate to a format that your phone accepts.

To convert from a PEM file to a DER file, you can use OpenSSL:

openssl x509 -inform PEM -outform DER -in Input.pem -out Output.der

If you don't have OpenSSL installed, you can find it in package manager.

You may need to use .cer as the output file extension. –  BillThor Apr 12 '11 at 1:31
