VO registration troubleshooting

Possible browser issues registering with eNMR VO:

  • using Mozilla Firefox:

you could get the message "Error code:ssl_error_internal_error_alert": if the case please disable TLS 1.0 from Tools/Options.../Advanced/Encryption tab

  • using Safari:

you could get the message: "Safari can't open the page https://voms2.cnaf.infn.it:8443/voms/enmr.eu because Safari can't establish a secure connection to the server voms.cnaf.infn.it".

Basically the steps to solve this problem are:

  1. Import the certificate in your keychain (basically double click on the certificate file). It will appear, most probabily, in the 'system' keychain with its private key.
  2. Select the certificate you just imported, and then do (command)I, or File->Get Info
  3. In the pop-up window expand the collapsed "Trust" menu and change the certificate policies.
  4. I would suggest 'always trust'  for all policies, but you could also
    enable it only for 'X.509 basic policy' that is how it's used for the
    https connection
Now, when you're connecting
to an https site Safari will ask you which certificate you want to be
used, and keychain will ask you if Safari is allowed to access to that
