Hi @nithinthomas
You can look at the network requests and try to work on correlation in order to achieve the login flow and the AEM redirection. On a high level you will have to use the cookie manager to pass the necessary cookies to each level also try to extract couple of variables like saml_request , saml response and tokens. Also in case if you have fiddler that will also help in formulating the requests
