No Peer Endpoint - At a loss

Hi All,

So I'm at a bit of a loss here. I'm working on integrating a system that has its own SAML SP built in, and am getting the "No peer endpoint available to which to send SAML response" message. I added protocol debug to my logs and have this:

10:32:27.031 - DEBUG [PROTOCOL_MESSAGE:91] -
<?xml version="1.0" encoding="UTF-8"?><samlp:AuthnRequest xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" AssertionConsumerServiceURL="" ID="mleklaicbkmclacdhegikepebmbaadbojljdondj" IsPassive="false" IssueInstant="2012-11-01T14:32:25Z" ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect" ProviderName="NetPartner" Version="2.0">
   <saml:Issuer xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion">NetPartner</saml:Issuer>
   <samlp:NameIDPolicy AllowCreate="true"/>

10:32:41.010 - INFO [Shibboleth-Access:73] - 20121101T143241Z|||/profile/SAML2/Redirect/SSO|
10:32:41.014 - ERROR [edu.internet2.middleware.shibboleth.idp.profile.AbstractSAMLProfileHandler:397] - No return endpoint available for relying party NetPartner

Here's what I have for the metadata for that SP:
<md:EntityDescriptor xmlns:md="urn:oasis:names:tc:SAML:2.0:metadata" entityID="NetPartner">
        <md:SPSSODescriptor protocolSupportEnumeration="urn:oasis:names:tc:SAML:2.0:protocol urn:oasis:names:tc:SAML:1.1:protocol urn:oasis:names:tc:SAML:1.0:protocol">
                <md:AssertionConsumerService index="1" isDefault="true" Binding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-Redirect" Location="" />

As you can see, the ACS in the metadata and the one in the SAML request appear to match (at least to me). Anyone have any ideas what I missed/fat-fingered?
