I've got a VS 2008 solution that's attempting to do a POC on validating a
user name and password using WSE 3.0 against a custom UserNameTokenManager.
The solution contains the MyAuthorizationLib project as the
UserNameTokenManager, a web service that references it, and a Windows app
that calls the web service to test a simple username/password validation
test.

I've modeled it after this project:

CodeProject: WebService Authentication with UsernameToken in WSE 3.0. Free
source code and programming help:
http://www.codeproject.com/KB/cpp/WebService_Authentication.aspx?display=PrintAll

That project works perfectly fine for me. However, mine does not - I get
the error below [1] when I attempt to call the HelloWorld method in the web
service:

Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports System.Text
Imports System.Xml
Imports System.Xml.Serialization
Imports Microsoft.Web.Services3

' To allow this Web Service to be called from script, using ASP.NET AJAX,
uncomment the following line.
' <System.Web.Script.Services.ScriptService()> _
<System.Web.Services.WebService(Namespace:="http://tempuri.org/")> _
<System.Web.Services.WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1)>
_
<Microsoft.Web.Services3.Policy("ServerPolicy")> _
<ToolboxItem(False)> _
Public Class Main
Inherits System.Web.Services.WebService

<WebMethod()> _
Public Function HelloWorld() As String
Return "Hello World" &
RequestSoapContext.Current.IdentityToken.Identity.Name
'Return "WORK, DAMMIT!"
End Function
End Class

The client code:

'init web service proxy - custom generated by wsewsdl3 against the
signature of Main.asmx in the web service
Dim myserviceProxy As New WSETestingClient.Main
Dim myserviceResponse As String

'init UsernameToken, password is the reverted string of username,
the same logic in AuthenticateToken of MyUserNameTokenManager class
Dim myToken = New UsernameToken("admin", "nimda",
PasswordOption.SendPlainText)

'Set the token onto the proxy
myserviceProxy.SetClientCredential(myToken)

'Set the ClientPolicy onto the proxy
myserviceProxy.SetPolicy("ClientPolicy")

Try
myserviceResponse = myserviceProxy.HelloWorld
Catch ex As Exception
System.Windows.Forms.MessageBox.Show(ex.ToString)
End Try

[1] Error:

There doesn't appear to be anything wrong with the section the error refers
to:

<microsoft.web.services3>
<diagnostics>
<trace enabled="true" input="InputTrace.webinfo"
output="OutputTrace.webinfo" />
</diagnostics>
<security>
<securityTokenManager>
<add type="MyAuthorizationLib.MyUserNameTokenManager,
MyAuthorizationLib"
namespace="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
localName="UsernameToken" />
</securityTokenManager>
</security>
<policy fileName="wse3policyCache.config" />

</microsoft.web.services3>

And my wse3policyCache.config file on the server contains:

What's the most common cause of these WSE040 errors?

Does the fact that I've had to roll my own WSE source files for VS 2008 have
anything to do with it - since there's no handy WSE Config Tool that
integrates with the IDE? (yes, I know the tool can be used standalone, but
it doesn't look like it's fully featured for a custom UserNameTokenManager)
