Identityserver 4 and Azure AD
Solution 1
You can use signin to Azure AD from IdentityServer just as you would use signin to IdentityServer from e.g. a Javascript or MVC app.
I have done this recently, and all you need to do is register OpenIdConnect options to Azure Ad like this:
public void ConfigureAuth(IAppBuilder app)
{
app.SetDefaultSignInAsAuthenticationType(CookieAuthenticationDefaults.AuthenticationType);
app.UseCookieAuthentication(new CookieAuthenticationOptions());
app.UseOpenIdConnectAuthentication(
new OpenIdConnectAuthenticationOptions
{
ClientId = clientId,
Authority = authority,
PostLogoutRedirectUri = postLogoutRedirectUri,
});
}
More info about this here: https://docs.microsoft.com/en-us/azure/active-directory/develop/active-directory-devquickstarts-webapp-dotnet
You should then in your Login action call the ChallengeAsync method:
var authenticationProperties = new AuthenticationProperties { RedirectUri = "your redirect uri" };
await HttpContext.Authentication.ChallengeAsync(your policy, authenticationProperties);
Then provide a callback method as a GET method then follow the External Login samples provided in IdentityServer samples: https://github.com/IdentityServer/IdentityServer4.Samples/blob/dev/Quickstarts/4_ImplicitFlowAuthenticationWithExternal/src/QuickstartIdentityServer/Quickstart/Account/AccountController.cs
Solution 2
There is a sample with Azure AD on github , forked from External Login sample provided in IdentityServer samples.
The sample also fixed a known issue "State parameter generated by middleware is too large for Azure AD #978"

I'm looking into using Identity Server 4 for authentication within a C# based MVC application. I'd like to use accounts stored in Azure AD as a source of valid users but the documentation only seems to refer to Google and OpenID & only mentions Azure in passing.
Does anybody know of any good documentation and/or tutorials on how to use Azure AD in the context of using it with Identity Server 4?
