동일한 유형의 여러 인증 스키마 지원

Question

IdentityServer4에서 작동하고 동일한 유형의 여러 외부 공급자 인 OpenIdConnect를 추가하려고 시도합니다. 그러나 나는 약간 문제점으로 달리고있다.

services.AddAuthentication() 
// Azure AD 
.AddOpenIdConnect("oidc", "Azure AD", x => 
{ 
    x.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme; 
    x.SignOutScheme = IdentityServerConstants.SignoutScheme; 
    x.ClientId = "some-client-id"; 
    x.Authority = "https://login.microsoftonline.com/common"; 
    x.ResponseType = OpenIdConnectResponseType.IdToken; 
    x.TokenValidationParameters = new TokenValidationParameters 
    { 
     ValidateIssuer = false 
    }; 
}) 
// Identity Server 
.AddOpenIdConnect("oidc", "My Other Identity Server", x => 
{ 
    x.SignInScheme = IdentityServerConstants.ExternalCookieAuthenticationScheme; 
    x.SignOutScheme = IdentityServerConstants.SignoutScheme; 
    x.ClientId = "some-other-client-id"; 
    x.Authority = "http://localhost:6000"; //Another Identity Server I want to treat as external provider 
    x.RequireHttpsMetadata = false; 
    x.ResponseType = OpenIdConnectResponseType.IdToken; 
    x.TokenValidationParameters = new TokenValidationParameters 
    { 
     ValidateIssuer = true 
    }; 
});

내가 그들에게 다른 계획을 제공하면, 그때는 외부 업체의 게시물 다시 다음과 같은 예외를 얻을.

솔루션이 CallbackPath 및 SignedOutCallbackPath 그래서 미들웨어가 실행되는 외부 프로 바이더를 알 수있는 특정 추가하는 것입니다 제안했다.
