Authentication fails with 2FA via DUO

[cement_head]

Attempting to sign-on to my google account to sync my calendar from my work organisation (WO). WO used DUO 2FA sign-on via a central authentication server. When trying to sign-on (sign-in) to my WO google account, the page gets redirected to my WO's CAS and the gdata-provider plug-in crashes and no sign-on can occur. Is there a way to circumvent this issue, or is there a workaround?
