I have a configured Okta and AEM SAML authentication handler. IDP initiated flow is working fine but my project requirement is to have a custom login page in AEM. Can someone guide me how to implement SP initiated flow where AEM SAML AUthentication handler and Okta are already configured. I tried searching a lot on web but i am able to comeup with right approach. on Submit of login button request has to go to Okta. How to send this request, what libraries do i need to use? and how is response processed? i will really appreciate if someone can provide as much information as you can.
