I regret to inform you that Plantisc-2 app on the Catania science gateway on https://184.108.40.206/ does not login through the IDPOpen. When you click on it you get this message:
Login to IDPOPEN - Unable to Respond
The login service was unable to identify a compatible way to respond to the requested application. This is generally due to a misconfiguration on the part of the application and should be reported to the application's support team or owner.
