[keycloak-user] Help to use Keycloak to test SSO feature in our application

Hi Folks, I'm new to this group. I'm an automation engineer by profession, the project that I'm working on requires the SSO feature introduced in our application to be tested. Initially we had plans to use okta but then it was decided to use some open source. I assumed keycloak would serve the purpose to me (I'm complete novice, please correct if I'm wrong). How we have used okta: we would configure our applicaton in it , add required users, groups etc. Then we would configure the wellknown url of okta application in our application. So the sso in our application would redirect to okta. Now I want to replace the same with keycloak. I brought up the local host , created a realm , user and client. I assumed the client in keycloak is similar to applications in okta. So configured the redirect url to my application. But when I configured the well known url of keycloak in my application it is not working. https://localhost:8443/auth/realms/demo/.well-known/openid-configuration. Please advice if my decision is right and if so what is that I'm missing in the configuration Thanks and Regards, Preethi
