With the identity assertion authentication method, the security
token generates a <wsse:UsernameToken> element that contains a <wsse:Username>
element. On the request sender side, a callback handler is invoked to generate
the security token. On the request receiver side, the security token is validated.
Unlike BasicAuth authentication, trust is established through the use of a
security token rather than through user name and password validation.
Before you begin
Important: There is an important distinction between Version
5.x and Version 6.0.x and later applications. The information
in this article supports Version 5.x applications only that are used
with WebSphere® Application
Server Version 6.0.x and later. The information does not apply to Version
6.0.x and later applications.
WebSphere Application Server provides
several different methods to secure your Web services. Identity assertion
authentication is one of these methods. You might also secure your Web services
using any of the following methods:
- XML digital signature
- XML encryption
- BasicAuth authentication
- Identity assertion authentication
- Signature authentication
- Pluggable token
About this task
To use identity assertion authentication to secure Web services,
complete the following tasks:
Procedure
- Secure the client for identity assertion authentication.
- Configuring the client for identity assertion: specifying the method
- Configuring the client for identity assertion: collecting the authentication method
- Secure the server for identity assertion authentication.
- Configuring the server to handle identity assertion authentication
- Configuring the server to validate identity assertion authentication information
Results
After completing these steps, you have secured your Web services by
using identity assertion authentication.
