	I'm sure this is a simple misundertanding on my part.  I've processed an assertion from an IdP and now I need to send an Attribute Query but am receiving an error when I try to send the SAML request.

	[code lang='vb'] 

	            Dim mycert As X509Certificates.X509Certificate2

	'load mycert here

	

		        Dim attlist As New List(Of AttributeDesignator)
	

		        attlist.Add(New AttributeDesignator("urn:mace:dir:attribute-def:eduPersonPrincipalName", "urn:mace:shibboleth:1.0:attributeNamespace:uri"))
	

		        attlist.Add(New AttributeDesignator("urn:mace:dir:attribute-def:eduPersonScopedAffiliation", "urn:mace:shibboleth:1.0:attributeNamespace:uri"))
	

		 


	            Dim myreq As New ComponentPro.Saml1.Request

	            Dim myqry As New ComponentPro.Saml1.AttributeQuery

	            myqry.Subject = mysub

	'mysub is subject from the original assertion

	            myqry.AttributeDesignators = attlist

	            myreq.Queries.Add(myqry)

	            myreq.Sign(mycert)

	 

	            myresp = myreq.Send(myurl, SoapVersion.Soapv12)

	'myurl is the attribute service location -  and I've tried Soapv11 as well

	 

	[/code]

	 

	On this last line I get the exception "Unable to send SAML request over SOAP."

	 

	Am I missing something from request/query - or am I using the component incorrectly?

	 

	Thanks.
