An example authentication action plugin for the Curity Identity Server. The plugin redirects the user to a given URL,
and only continues with the authentication if it can verify that the external action succeeded. It achieves that by generating
a random UUID and redirecting the user to the external system and passing the UUID in a status query parameter. When
the authentication is continued, the action makes a GET request to the external system again adding the status parameter
with the same UUID. The action expects the endpoint to return a 200 response with JSON containing two fields: externalUserId
and externalStatus. Values of these two fields are then added to the Authorization Parameters.
Build the plugin by issuing the command mvn package. This will produce a JAR file in the target directory, which can be installed.
To install the plugin, copy the compiled JAR (and all of its dependencies) into the :file:`${IDSVR_HOME}/usr/share/plugins/redirect-action` on each node, including the admin node. For more information about installing plugins, refer to the curity.io/plugins.
For a list of the dependencies and their versions, run mvn dependency:list. Ensure that all of these are installed in
the plugin group; otherwise, they will not be accessible to this plug-in and run-time errors will result.
