Sharepoint Authentication with OWIN

Question

Hello,
I am working on Publishing site on SP 2013 with Object Model. I tried to use OWIN Middleware to authenticate the customer.
The steps I follow are:
-> deployement of OWIN assemblies in the web application: OK
-> Startup Class: OK
public void Configuration(IAppBuilder app)
System.Diagnostics.Trace.TraceInformation("OWIN Startup configuration is running");
app.UseCookieAuthentication(new CookieAuthenticationOptions
AuthenticationType = "Application",
AuthenticationMode = Microsoft.Owin.Security.AuthenticationMode.Passive,
LoginPath = new PathString("/3wc/en-gb/Pages/login.aspx")
-> Login.aspx with a postback:
protected void btnLogin_Click(object sender, EventArgs e)
try
var ctx = this.Context.Request.GetOwinContext();
var authenticationManager = ctx.Authentication;
var user = authenticationManager.User;
if (user != null)
var identity = user.Identities.SingleOrDefault(id => id.AuthenticationType == "Application");
if (identity != null && identity.IsAuthenticated)
System.Diagnostics.Trace.TraceInformation("NEVER EXECUTED!!");
var claims = new List<System.Security.Claims.Claim>();
claims.Add(new System.Security.Claims.Claim(ClaimTypes.Name, "Chris"));
identity = new System.Security.Claims.ClaimsIdentity(claims, "Application");
authenticationManager.SignIn(new AuthenticationProperties() { IsPersistent = true }, identity);
catch (Exception ex)
this.lbStatus.Text = "Something went wrong: " + ex.ToString();
I was expecting that if I click twice on the button, the debugger will step on System.Diagnostics.Trace.TraceInformation("NEVER EXECUTED!!"); . But is is never executed.
Thanks a lot for your help
Chris
