How to add additional request parameters in wso2 retrying?

Question

I need to add one parameter to redirect. When authentication fails WSO2 redirects to login page with &authFailure=true&authFailureMsg=login.fail.message request parameters.

I could not add some additional parameter to it by changing org.wso2.carbon.identity.application.authenticator.basicauth.BasicaAuthenticator class messages.

Are there any ways of doing it?

Answer 1

I could not change BasicAuthenticator.class. Added additional parameters by registering my LocalBasicAuthenticator where functions are the same as BasicAuthenticator but you can add query params and modify it. Then replace jar in components/dropins and change local authentication in your Service Provider.
