When trying to connect to the KEK VOMS server I see 'SSL_ERROR_HANDSHAKE_FAILURE_ALERT'?

In order to create the necessary secure connection to the KEK VOMS server, your browser needs to accept the VOMS server's certificate. Click 'Advanced' /  'Add exception' / 'Get certificate' / 'Store permanently' / 'Confirm' .

Connection errors such as 'SSL_ERROR_HANDSHAKE_FAILURE_ALERT' are due to old or missing CA certificates in your browser. You might want to check Preferences / Advanced / Certificates / View Certificates / Servers and Authorities . Also consider to use another browser. We have good experiences with firefox and we saw also safari on MAC working. From our experience there is usually someone in your group or institute who managed.

How to test my Grid user certificate in ~/.globus ?

Grid users usually have exported their Grid user certificate to ~/.globus to use it with Grid commands such as 'voms-proxy-init', 'dirac-proxy-init', or 'gb2_proxy_init'. The following commands may help to investigate the situation.

The directory:

> cd ~/.globus

> ls -l

-r--r--r-- 1  usercert.pem

-r-------- 1  userkey.pem

 

Checking if public (cert) and private (key) match:

 

> openssl x509 -noout -modulus -in usercert.pem | openssl md5
> openssl rsa -noout -modulus -in userkey.pem | openssl md5

 

Checking subject, issuer, and validity dates:

> openssl x509 -subject -issuer -email -dates -noout -in ~/.globus/usercert.pem

 

Recreating a single file with public and private key to be improted into a broser:

> openssl pkcs12 -export -out my_cert.p12 -inkey userkey.pem -in usercert.pem
