I found the final solution, this is the code of my OWIN startup class:
public void Configuration(IAppBuilder app)
{
app.MapSignalR();
// Enable the application to use a cookie to store information for the signed i user
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Home/Index")
});
// Use a cookie to temporarily store information about a user logging in with a third party login provider
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
app.UseMicrosoftAccountAuthentication(new MicrosoftProvider().GetAuthenticationOptions());
app.UseTwitterAuthentication(new TwitterProvider().GetAuthenticationOptions());
app.UseFacebookAuthentication(new FacebookProvider().GetAuthenticationOptions());
app.UseGoogleAuthentication(new GoogleProvider().GetAuthenticationOptions());
}
Making myself some coffee, I thought “What about mapping SignalR AFTER the authentication, and voila! Now it’s workign as expected.
public void Configuration(IAppBuilder app)
{
// Enable the application to use a cookie to store information for the signed i user
app.UseCookieAuthentication(new CookieAuthenticationOptions
{
AuthenticationType = DefaultAuthenticationTypes.ApplicationCookie,
LoginPath = new PathString("/Home/Index")
});
// Use a cookie to temporarily store information about a user logging in with a third party login provider
app.UseExternalSignInCookie(DefaultAuthenticationTypes.ExternalCookie);
app.UseMicrosoftAccountAuthentication(new MicrosoftProvider().GetAuthenticationOptions());
app.UseTwitterAuthentication(new TwitterProvider().GetAuthenticationOptions());
app.UseFacebookAuthentication(new FacebookProvider().GetAuthenticationOptions());
app.UseGoogleAuthentication(new GoogleProvider().GetAuthenticationOptions());
app.MapSignalR();
}
