NERSC Online Certificate Authority

The NERSC Online Certificate Authority (CA) issues short-lived grid certificates (valid up to 1 million seconds, or approximately 11 days) to NERSC users, based on an LDAP authenticated "myproxy-logon" client request. The NERSC Online CA is operated under the Short Lived Credential Service (SLCS) profile of the International Grid trust Federation (IGTF).

CA Information

Getting a Certificate:

NERSC Online CA issues certificates to clients that use the myproxy protocol. The NERSC Online CA is located at nerscca.nersc.gov (also known as slcs.nersc.gov).

To acquire a certificate you must have a valid NERSC account. You can get a certificate by issuing the following command:

myproxy-logon -s nerscca.nersc.gov

You will need to enter your NERSC NIM/LDAP password to authenticate your identity. If the authentication succeeds the myproxy client will create a short lived certificate for use on the grid.
