REST Authentication

Be Careful

This documentation describes how to delegate and submit authentication requests to a remote REST endpoint. It has nothing to do with the native CAS REST API, whose configuration and caveats are documented here.

REST authentication is enabled by including the following dependencies in the WAR overlay:

1
2
3
4
5
<dependency>
    <groupId>org.apereo.cas</groupId>
    <artifactId>cas-server-support-rest-authentication</artifactId>
    <version>${cas.version}</version>
</dependency>

This allows the CAS server to reach to a remote REST endpoint via a POST for verification of credentials. Credentials are passed via an Authorization header whose value is Basic XYZ where XYZ is a Base64 encoded version of the credentials. The response that is returned must be accompanied by a 200 status code where the body should contain id and attributes fields, the latter being optional, which represent the authenticated principal for CAS.
