Executive Summary: A researcher or educator (hereafter referred to as “the user”) wants to use his/her community identity to obtain credentials that can be used to authenticate with the OpenStack API on a community resource.
No effort or changes are proposed at this time. Current users of OpenStack APIs on the one XSEDE resource that offers user access, Jetstream, are satisfied with the current authentication mechanism offered by Jetstream, and the Jetstream Service Providers (Indiana University and TACC) are satisfied with administering the current mechanism.
|Component||User facing?||Component’s role in the capability|
|Globus Auth||yes||Globus Auth is XSEDE's Web Single Sign-On (Web SSO) service. Beyond supporting user authentication for Web browser-based "Web apps," Globus Auth also provided OAuth2-based authentication for use by REST APIs. OpenStack APIs can use OAuth2 access tokens for authentication. Thus, Globus Auth can be used to protect access to OpenStack APIs, including user authentication.|
|Service Provider IaaS (Cloud) Services||yes||The cloud resources offered by XSEDE Service Providers (SPs) are the resources that are to be accessed and used once authentication via Single Sign-On is accomplished.|
