Hi,

I'm trying to create a custom authentication plugin for WMS 2009 in C#.

I managed to implement something that for some reason blocks all requests...

[ComVisible(true)]
[Guid("C0A0B38C-C4FE-43B5-BE9E-C100A83BBCEE")]
public class AuthenticationPlugin : IWMSBasicPlugin, IWMSAuthenticationPlugin, IWMSAuthenticationContext
    private const string SubKey = "SOFTWARE\\Microsoft\\Windows Media\\Server\\RegisteredPlugins\\Authentication\\{C0A0B38C-C4FE-43B5-BE9E-C100A83BBCEE}";

    [ComRegisterFunction]
    public static void RegisterFunction(Type t)
    {
        try
        {
            RegistryKey regHKLM = Registry.LocalMachine;
            regHKLM = regHKLM.CreateSubKey(SubKey);
            regHKLM.SetValue(null, "UC WMS Authentication plugin");

            RegistryKey regHKCR = Registry.ClassesRoot;
            regHKCR = regHKCR.CreateSubKey("CLSID\\{C0A0B38C-C4FE-43B5-BE9E-C100A83BBCEE}\\Properties");
            regHKCR.SetValue("Name", CustomC WMS Authentication plugin");
            regHKCR.SetValue("Author", "Me");
            regHKCR.SetValue("CopyRight", "Copyright 2009. All rights reserved");
            regHKCR.SetValue("Description", "Enables custom WMS authentication");
        }
        catch (Exception error)
        {
            Console.WriteLine(error.Message, "Inside RegisterFunction(). Cannot Register.");
        }
    }

    [ComUnregisterFunction]
    public static void UnRegisterFunction(Type t)
    {
        try
        {
            RegistryKey regHKLM = Registry.LocalMachine;
            regHKLM.DeleteSubKey(SubKey);

            RegistryKey regHKCR = Registry.ClassesRoot;
            regHKCR.DeleteSubKeyTree("CLSID\\{C0A0B38C-C4FE-43B5-BE9E-C100A83BBCEE}");
            regHKCR.DeleteSubKeyTree("CSEventTest.CSEventPlugin");
        }
        catch (Exception error)
        {
            Console.WriteLine(error.Message, "Cannot delete a subkey.");
        }
    }

    #region IWMSBasicPlugin Members

    public void InitializePlugin(IWMSContext serverContext, WMSNamedValues namedValues, IWMSClassObject classFactory)
    {
    }

    public void ShutdownPlugin()
    {
    }

    public void EnablePlugin(ref int flags, ref int heartbeatPeriod)
    {
    }

    public void DisablePlugin()
    {
    }

    public object GetCustomAdminInterface()
    {
        return null;
    }

    public void OnHeartbeat()
    {
    }

    #endregion

    #region IWMSAuthenticationPlugin Members

    public IWMSAuthenticationContext CreateAuthenticationContext()
    {
        return (IWMSAuthenticationContext)this;
    }

    public int GetFlags()
    {
        return Convert.ToInt32(WMS_AUTHENTICATION_FLAGS.WMS_AUTHENTICATION_ANONYMOUS, CultureInfo.InvariantCulture);
    }

    public string GetPackageName()
    {
        return "Custom WMS Authentication";
    }

    public string GetProtocolName()
    {
        return "Basic";
    }

    #endregion

    #region IWMSAuthenticationContext Members

    public void Authenticate(object responseBlob, IWMSContext userContext, IWMSContext presentationContext, IWMSCommandContext commandContext, IWMSAuthenticationCallback callBack, object context)
    {
        callBack.OnAuthenticateComplete(WMS_AUTHENTICATION_RESULT.WMS_AUTHENTICATION_SUCCESS, null, context);
    }

    public IWMSAuthenticationPlugin GetAuthenticationPlugin()
    {
        return (IWMSAuthenticationPlugin)this;
    }

    public string GetImpersonationAccountName()
    {
        return String.Empty;
    }

    public int GetImpersonationToken()
    {
        return 0;
    }

    public string GetLogicalUserID()
    {
        return this.GetImpersonationAccountName();
    }

    #endregion
}

Can anyone spot why this is happening?

Also, is there any way I could have a look at the code for the standard Anonymous Authentication plugin already installed on the server? Is it in an assembly somewhere?

Thanks.
