Hi Ashish,

Have you tried following this docs? Integrate Azure AD using OpenID Connect (optimizely.com)?

It's about integrating Optimizely CMS with Azure AD, but I think it would be the same for other providers. 

Thanks for the response. Does that still seem to be for the Optimizely admin interface/users? The reason I am asking is because. 

1. It has these instrutions... "Create WebAdmins, WebEditors and Administartors app role: This is an example of app roles that declare WebAdmins and WebEditors. You can modify it according to your application roles."
2. Doesn't specify how to wire up your "login button"

Ashish, this would be pretty standard for any kind of Identity Provider / SSO Integration, as part of you implementation you can Synch the roles you setup in oAuth to the CMS, this is also detailed in the blog mentioned by Bac, 

                    // Syncs user and roles so they are available to the CMS
                    var synchronizingUserService = ctx
                        .HttpContext
                        .RequestServices
                        .GetRequiredService<ISynchronizingUserService>();

                    await synchronizingUserService.SynchronizeAsync(claimsIdentity);

You are also able to map virtual roles either via appSettings or Programatically, see here for information : https://docs.developers.optimizely.com/content-cloud/v12.0.0-content-cloud/docs/virtual-roles

The interface for logging a user in will all be hadled via the provider be it Auth0, Okta or Azure AD etc
