I'm trying to implement a custom username token manager, with little
success.

My service and client both have WSE2 enabled.  This is an ASMX web
service. Authentication works without the custom token, sending password
in PlainText.

As soon as I change it to send a hashed password, and enable
MyUsernameTokenManager, it gives me the following error:

Additional information:
System.Web.Services.Protocols.SoapHeaderException: Server unavailable,
please try later ---> System.Configuration.ConfigurationException:
WSE032: There was an error loading the microsoft.web.services2
configuration section. ---> System.Configuration.ConfigurationException:

configuration file.

I have my username token manager defined as follows:

public class MyUsernameTokenManager : UsernameTokenManager
    {
        protected override string AuthenticateToken(UsernameToken token)
        {   
            return "password";  //for dev only.. logic to come later.
        }
    }

My web.config file looks like this:

<security>
      <securityTokenManager
type="Macgregor.Mambo.PrimeBroker.MyUsernameTokenManager,
Macgregor.Mambo.PrimeBroker"
xmlns:wsse="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd"
qname="wsse:UsernameToken" />
    </security>

I'm a little confused about the syntax of the type attribute.  Why is it
namespace.class, namespace?  (I took this syntax from the HOL.)

Why can't my web service load MyUsernameTokenManager?

Thanks.
