Please note:
  • The procedure to request robot certificates is now fully automated, and it's no longer necessary to request permissions to Certification Authority administrators with a digitally signed email
  • If you do not satisfy the criteria to request a robot certificate, no exceptions are possible.

Grid Robot certificates

Robots, also known as automated clients, are entities that perform tasks without human intervention.

These procedures generally run using an identity with the necessary privileges to perform their tasks. If automated tasks need to authenticate using a certificate provided by the CERN Grid Certification Authority, a robot certificate should be used.

Robot certificates can only be issued to valid Service accounts.

The purpose of a robot certificate is to allow the team performing the automated tasks to authenticate without needing individual user certificates. Moreover, if the certificate subject is used by the application, it will not be necessary to modify the application's configuration each time a new certificate is issued.

A robot certificate must not be used for the following purposes:

  • To share a certificate so that people don't need to enter individual credentials.
  • To obtain a certificate for a Service account.
