Attribute resolver warning on start-up

[Wessel, Keith]

Hi, all,

Since moving to V3, we're seeing the following on start-up:

2015-07-02 11:48:51,640 - WARN [net.shibboleth.idp.saml.attribute.mapping.AbstractSAMLAttributeMapper:223] - Scoped Attribute Mapper 'MapperForeduPersonScopedAffiliation': Attribute 'urn:oid:1.3.6.1.4.1.5923.1.1.1.9' value conversion yielded no suitable values

Yet we get valid scoped attribute values for eduPersonScopedAffiliation released to SPs. Below is my definition from attribute-resolver.xml. What's causing this warning?

    <resolver:AttributeDefinition id="eduPersonScopedAffiliation" xsi:type="ad:Scoped"
         scope="%{idp.scope}" sourceAttributeID="eduPersonAffiliation">
         <resolver:Dependency ref="myLDAP" />
 
        <resolver:AttributeEncoder xsi:type="SAML1ScopedString" xmlns="urn:mace:shibboleth:2.0:attribute:encoder"
             name="urn:mace:dir:attribute-def:eduPersonScopedAffiliation" />
 
        <resolver:AttributeEncoder xsi:type="enc:SAML2ScopedString" name="urn:oid:1.3.6.1.4.1.5923.1.1.1.9" friendlyName="eduPersonScopedAffiliation" encodeType="false" />
     </resolver:AttributeDefinition>
       
Thanks,
Keith
