Define means for an authentication handler to provide information on the
implemented authentication type
--------------------------------------------------------------------------------------------------------
Key: SLING-1382
URL: https://issues.apache.org/jira/browse/SLING-1382
Project: Sling
Issue Type: New Feature
Components: Commons
Reporter: Felix Meschberger
Assignee: Felix Meschberger
Fix For: Commons Auth 1.0.0
The AuthenticationHandler interface should be extended with the following two
constants:
/**
* The name of the service registration property (single string) providing
* the authentication type of authentication handler. This is the same value
* as will be returned as the {...@link AuthenticationInfo#getAuthType()
* authentication type} returned by the
* {...@link #extractCredentials(HttpServletRequest, HttpServletResponse)}
* method.
* <p>
* <p>
* This property is optional but allows the client to optionally select the
* authentication handler which will actually request credentials upon the
* {...@link #requestCredentials(HttpServletRequest, HttpServletResponse)}
* method.
*
* @see #REQUEST_LOGIN_PARAMETER
*/
static final String TYPE_PROPERTY = "authtype";
/**
* The request parameter which may be used to explicitly select an
* authentication handler by its {...@link #TYPE_PROPERTY type} if
* authentication will be requested through
* {...@link #requestCredentials(HttpServletRequest, HttpServletResponse)}.
*
* @see #requestCredentials(HttpServletRequest, HttpServletResponse)
* @see #TYPE_PROPERTY
*/
static final String REQUEST_LOGIN_PARAMETER = "sling:authRequestLogin";
This allows for client-side selection of a concrete authentication handler to
use for requesting credentials and also to inquire about authentication types
of registered authentication handlers.
