Introduction to Authentication

Overview

In Fuse Services Framework, an application can be set up to use authentication through a combination of policy assertions in the WSDL contract and configuration settings in Spring XML.

Note

Remember, you can also use the HTTPS protocol as the basis for authentication and, in some cases, this might be easier to configure. See Authentication Alternatives.

Steps to set up authentication

In outline, you need to perform the following steps to set up an application to use authentication:

  1. Add a supporting tokens policy to an endpoint in the WSDL contract. This has the effect of requiring the endpoint to include a particular type of token (client credentials) in its request messages.

  2. On the client side, provide credentials to send by configuring the relevant endpoint in Spring XML.

  3. (Optional) On the client side, if you decide to provide passwords using a callback handler, implement the callback handler in Java.

  4. On the server side, associate a callback handler class with the endpoint in Spring XML. The callback handler is then responsible for authenticating the credentials received from remote clients.
