I have SSO configured with a auth server which hosts login page and sso functionality using OAuth2. I have several clients which redirect to this auth server login page whenever authentication is required.
What I am trying to achieve is to not redirect to this auth server login page, instead somehow if a client wants to have its own custom login page then user fills in username password there and internally client connects to auth server for authentication. Hence, a user never leaves the client website.
Is it possible to achieve?
