XSEDE federated identity plugin
Carol has requested an XSEDE login plugin, similar to the Purdue login on the login screen.
The authentication protocol that XSEDE/TerraGrid uses is already configured on springboard for the login there. Springboard is currently configured to only allow TerraGrid accounts to login. Carol would like to allow, as an alternative to a hub account, those with XSEDE accounts to login to diagrid.
