Pablo,

Thanks for the reply.. much appreciated!

My client is connecting to a custom STS server.. i have no access to the
server source - it is a govt server implementing the msoft GSO offering,

The only thing "custom" about my STS server is that it returns its own
"tokens" in its xml format.  I create standard Oasis username tokens, in the
format below ...  How can i tell WSE3 to use this usernametoken format? not
the new 2005 oasis version?

<wsse:UsernameToken
   xmlns:wsu="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-utility-1.0.xsd"
   wsu:Id="SecurityToken-c80775e7-b8dc-46d4-9312-dbfa65a2b6e9">
    <wsse:Username>513FDQ37JILL</wsse:Username>
    <wsse:Password
Type="http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-username-token-profile-1
.0#PasswordDigest">
        6MVcBZAS0SQpitXrRsXntcbugHw=
    </wsse:Password>
    <wsse:Nonce>C1CRDaeRoqFSrjjMdh3TIA==</wsse:Nonce>
    <wsu:Created>2004-06-28T13:00:32Z</wsu:Created>
</wsse:UsernameToken>

I have reverted all my code back to WSE2 and with a bit of "fiddling" i now
have WSE2 working with .NET2 and VS2005... is this a recommended approach?

Below is an example of my WSE2 and WSE3 code, however i cannot see where
your
example  using [SoapMethod("01/2005/Issue")] would fit in,

The WSE2 code to do this looks similar to :-  [ seeWSE2
CustomXmlSecurityToken example ]
MyClass : SecurityTokenServiceClient
{
 public const string TokenServiceAppliesTo =
"urn:XXX-System-Services:external:1.0.0:XXXWebServices";
 public const string TokenType                    =
"urn:XXX-System-Services:external:1.1.1:mytoken#mytoken";
 SecurityToken      token = UsernameToken(user, passwd);

 AppliesTo appliesto = new AppliesTo(TokenServiceAppliesTo);
 RequestSecurityToken rst = RequestSecurityToken(TokenType,  token,
appliesto);
 RequestSecurityTokenResponse rstr = this.IssueSecurityToken(rst);
 return rstr.RequestedSecurityToken.SecurityToken as MySecurityToken;
}

Using WSE3
MyClass : SecurityTokenServiceClient
{
 public const string TokenServiceAppliesTo =
"urn:XXX-System-Services:external:1.0.0:XXXWebServices";
 public const string TokenType                    =
"urn:XXX-System-Services:external:1.1.1:mytoken#mytoken";

 AppliesTo appliesto = new AppliesTo(TokenServiceAppliesTo);
 RequestSecurityToken rst = RequestSecurityToken(TokenType)
 rst.AppliesTo = appliesTo

 // add the username token
 UsernameForCertificateAssertion assertion = new
UsernameForCertificateAssertion();
 assertion.UsernameTokenProvider = new UsernameTokenProvider(username,
"BadPassword");

 Policy policy = new Policy();
 policy.Assertions.Add(assertion);
 rst.SetPolicy ( policy )

 RequestSecurityTokenResponse rstr = this.IssueSecurityToken(rst);
 return rstr.RequestedSecurityToken.SecurityToken as MySecurityToken;
}
