Method Detail

login

public abstract void login(Subject subject,
                           CallbackHandler handler)
                    throws LoginException

Log in to this provider.

The provider relies on a CallbackHandler to obtain authentication information from the caller (a PIN, for example). If the caller passes a null handler to this method, the provider uses the handler set in the setCallbackHandler method. If no handler was set in that method, the provider queries the auth.login.defaultCallbackHandler security property for the fully qualified class name of a default handler implementation. If the security property is not set, the provider is assumed to have alternative means for obtaining authentication information.

Parameters:: subject - the Subject which may contain principals/credentials used for authentication, or may be populated with additional principals/credentials after successful authentication has completed. This parameter may be null.; handler - the CallbackHandler used by this provider to obtain authentication information from the caller, which may be null
Throws:: IllegalStateException - if the provider requires configuration and Provider.configure(java.lang.String) has not been called; LoginException - if the login operation fails; SecurityException - if the caller does not pass a security check for SecurityPermission("authProvider.name"), where name is the value returned by this provider's getName method

logout

public abstract void logout()
                     throws LoginException

Log out from this provider.

Throws:: IllegalStateException - if the provider requires configuration and Provider.configure(java.lang.String) has not been called; LoginException - if the logout operation fails; SecurityException - if the caller does not pass a security check for SecurityPermission("authProvider.name"), where name is the value returned by this provider's getName method

setCallbackHandler

public abstract void setCallbackHandler(CallbackHandler handler)

Set a CallbackHandler.

The provider uses this handler if one is not passed to the login method. The provider also uses this handler if it invokes login on behalf of callers. In either case if a handler is not set via this method, the provider queries the auth.login.defaultCallbackHandler security property for the fully qualified class name of a default handler implementation. If the security property is not set, the provider is assumed to have alternative means for obtaining authentication information.

Parameters:: handler - a CallbackHandler for obtaining authentication information, which may be null
Throws:: IllegalStateException - if the provider requires configuration and Provider.configure(java.lang.String) has not been called; SecurityException - if the caller does not pass a security check for SecurityPermission("authProvider.name"), where name is the value returned by this provider's getName method
