ASP.NET Core Web App using Work (Azure AD) Authentication works debugging locally, but not after publish to Azure - azure

Question

My ASP.NET Core web app works great when running and debugging locally, but fails to run once published to Azure.
I enabled Organizational Authentication and selected the appropriate domain upon publishing.
The appropriate reply URL was registered
After I publish to Azure I get this error:
An unhandled exception occurred while processing the request.
OpenIdConnectProtocolException: Message contains error: 'invalid_client', error_description: 'AADSTS70002: The request body must contain the following parameter: 'client_secret or client_assertion'.
Trace ID: 640186d6-9a50-4fce-ae39-bbfc1caf2400
Correlation ID: 622758b2-ca52-4bb0-9a98-e14d5a45cf80
Timestamp: 2017-04-19 16:36:32Z', error_uri: 'error_uri is null'.
I'm assuming that it's because the Client Secret needs to be stored in Azure somewhere; however, the value in secrets.json did not work when I added it as an App Setting (invalid client secret error) as I saw someone was able to do on another post. Also not sure if putting the value of "Authentication:AzureAd:ClientSecret" in Azure AppSettings is a good idea anyway.

Not sure if this is useful to anyone or not. But i receive a similar error message.
OpenIdConnectProtocolException: Message contains error: 'invalid_client', error_description: 'error_description is null', error_uri: 'error_uri is null'.
Microsoft.AspNetCore.Authentication.OpenIdConnect.OpenIdConnectHandler+<RedeemAuthorizationCodeAsync>d__22.MoveNext()
The solution for me was to provide a secret in the token service
,new Client
{
ClientId = "Testclient",
ClientName = "client",
ClientSecrets =
{
new Secret("secret".Sha256())
},
//Hybrid is a mix between implicit and authorization flow
AllowedGrantTypes = GrantTypes.Hybrid,
And provide the secret in the client
app.UseOpenIdConnectAuthentication(new OpenIdConnectOptions
{
//The name of the authentication configuration.. just incase we have multiple
AuthenticationScheme = "oidc",
//Represents where to store the identity information -> which points to the cookie middleware declared above
SignInScheme = "Cookies",
//where the token service reside -> system will configure itself by invoking the discovery endpoint for the token service
Authority = "http://localhost:5000",
RequireHttpsMetadata = false,
ClientId = "Testclient",
ClientSecret = "secret",
//hybrid flow -grant type
ResponseType = "code id_token",
Hopefully this helps someone

Somehow I the Azure AD IDs needed for the proper Azure Active Directory App Registration were mixed up. There were 2 App Registration entries and the ClientID and TenentID's didn't match up with the local. So I synchronized the Client and Tenent IDs with one of the App Registration entries, and made sure the Client Secret was in App Settings, and it worked properly.
I verified these steps with this fine example Win's GitHub repository and they match now.
