title: How to Use atTask REST API with Federated SSO
body: <p>I need to be able to close tasks through the rest AP but our organization is using federated login using Active Directory. While, I can get read-only access to a users tasks by taking advantage of cookie authentication, there is apparently no documented way to acquire a session id that would give me write-access. Hitting the login link with username/password does not work due to the federated login. Is there an alternate way have authenticated write-access on a per-user basis (not using administrative accounts) ?</p>
