Interface StepUpAuthHandler

public interface StepUpAuthHandler

This is the plug-point for custom step up handler implementations. The object is instantiated as a singleton and is supposed to be thread safe. NOTE: This API may only be used in the scope of an HTTP request in WebSphere Portal, i.e. within a theme. The API can not be invoked directly by a custom servlet.

Since:

6.1

Note:

This interface is designed to be implemented by clients.

establishAuthLevel

java.lang.String establishAuthLevel(javax.servlet.http.HttpServletRequest request,
                                    javax.servlet.http.HttpServletResponse response)
                                    throws SecurityException

This method is responsible for establishing the authentication level that is associated with this step-up authentication handler implementation.
If this step requires sending an HTTP redirect, the redirect URL has to be passed to the caller as return value of this method. This method is not allowed to directly send the HTTP redirect using the response object. If the method returns null, no redirect will be triggered and the authentication level is assumed to be successfully established. In this case (and only in this case) request processing is continued.

Parameters:

request - The current request.

response - The current response.

Returns:

A redirect target URL or null.

Throws:

SecurityException - If an unrecoverable problem occurs.
