Implementing a custom FormsAuthenticationProvider using Owin, Katana, and Nancy - nancy

Question

I am working on implementing a custom FormsAuthenticationProvider and I'm getting a middleware conversion error.
No conversion available between System.Func`2[System.Collections.Generic.IDictionary`2
[System.String,System.Object],System.Threading.Tasks.Task] and Microsoft.Owin.OwinMiddleware
Parameter name: signature
My stack includes
Owin
Katana
Nancy
My specific question would be any advice on where to look for an example on how to implement a custom FormsAuthenticationProvider? Unless someone can spot my problem.
My implementation looks like:
Startup.cs
app.UseFormsAuthentication(new FormsAuthenticationOptions
{
LoginPath = "/login",
LogoutPath = "/logout",
CookieHttpOnly = true,
AuthenticationType = Constants.ChainLinkAuthType,
CookieName = "chainlink.id",
ExpireTimeSpan = TimeSpan.FromDays(30),
Provider = kernel.Get<IFormsAuthenticationProvider>()
});
If I remove the app.UseFormsAuthentication(...) the application runs without error.

Can you try updating the version of Microsoft.Owin.Host.SystemWeb package to the latest RC as well and try? You have all other Owin* dlls in rc but this is 1.0.0. Could be causing the issue. Also please use Microsoft.Owin.Security.Cookies instead of Microsoft.Owin.Security.Forms. The Forms package has been renamed to Cookies now.
