In 2016, US ATLAS will cease to use OSG-supplied certificates, in favor of certificates issued by the CERN certificate authority (CA). To ensure minimal impact to your ATLAS privileges through this transition, US ATLAS encourages you to obtain a personal certificate from the CERN CA (if you don't yet have one), and add it to your existing ATLAS VO membership.
