Laser authentication along with OAuth authentication

I need to find a solution to the problem. So I am developing a website and I am stuck with authentication. First of all, we use Azure Active Directory to store users. So I found WebApp-WebAPI-OpenIDConnect-DotNet and did it for my needs. While it works. But now I have to implement external logins as well (facebook, twitter, etc.). Therefore, I have commented on all the previous work during the time when I work with this problem. I had to rewrite some UserManager and UserStore classes, but got it to work. I can login with facebook. But now that I need to merge both of these logins together, they don't work. They seem to come into conflict within the frame. Login to Facebook requiresapp.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);

but the moment I enable this the boolean login stops working. If I comment on this, azure login works, facebook doesn't. Can anyone help me fix this? I will provide mineStartup.Auth.cs
