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 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.
