How to Set Up OAuth 2.0 Support in Vidispine

Applies to

OAuth 2.0 is a technique for enabling authorization of users without having to deal with the secrets of the user. It also allows you to create truly single sign-on solutions.

Summary

Vidispine supports OAuth 2.0 from version 4.4, to make integrations with your systems easier, using, for example, Azure AD or Google API. This article explains how to configure Vidispine with OAuth 2.0.

Background.

OAuth works by using the redirect functionality in the HTTP protocol. This means that neither your application or the Vidispine API will ever see the user's password. Instead, the user will log in directly to the Authorization Server (e.g. Azure AD, or Google API). Once logged in, the user's browser will receive an authorization code and a redirect request back to your application. That authorization code is used to get a resource token (JWT). The resource token is then sent to Vidispine for all API calls using Authorization: Bearer HTTP header, instead of Basic authentication.

Authorization flow

Token Validation

When Vidispine receives the token, it has to be validated. There are today three ways of doing this. If you want to authenticate against a service that provides an API to validation (e.g. Google API), you just have to enter the endpoint information in your shiro.ini. As usual, apidoc has the details. In order to reduce the load on the authorization service (and provide you with a faster API), the information is cached in Vidispine.

If you use Azure AD, you can use Federation Metadata instead. Here, Vidispine will download a set of X.509 certificates in a separate process from the Authorization source. This is done in the background, so it will not cause any delay to the API. Also, HTTPS is used to secure the transfer.

A third alternative is to provide Vidispine with a set of static X.509 certificates directly in the shiro.ini file.
