Instructions for Certificates in Browsers

WARNING: This page is obsolete.

Please look at https://atlas-software.docs.cern.ch/analysis/analysis_tutorial/basicSetup/grid_cert/.

We provide instructions for Firefox below and support only that browser at this time.

First: CERN ROOT Certificates

Trust Existing CERN ROOT Certificate

If you already have the CERN ROOT Certificates, make sure you trust them.

• Launch Firefox
• Open Preferences
• Go to Privacy and Security
• Scroll Down to Certificates

• Click on OK when done

Install New CERN ROOT Certificates

If you do not have the CERN ROOT Certificates:

• Launch Firefox

Second, Import Grid User Certificate

Check Existing Grid User Certificate

If you already have imported your grid user certificate into your browser, check they are valid.

• Launch Firefox
• Open Preferences
• Go to Privacy and Security
• Scroll Down to Certificates
• Click on "View Certificates"
• Select the tab "Your Certificates"

• Check the validity date
• Close that view box
• If Validity is expired, delete that certificate
• Click OK

• First ensure that you have the p12 file. (See these instructions if you need to convert.)
• Launch Firefox
• Open Preferences

• Click on "View Certificates"
• Select the tab "Your Certificates"
