Method Detail |

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