RequestedAttribute

[Massimiliano Masi]

Hi All, 

Sorry in advance for the probably stupid question. 

I’m creating a SPSSODescriptor, and I want to add two RequestedAttribtues, like in the example of SAML-METADATA. 

<RequestedAttribute
NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri"
Name="urn:oid:1.3.6.1.4.1.5923.1.1.1.7"
FriendlyName="eduPersonEntitlement">
<saml:AttributeValue>
https://ServiceProvider.com/entitlements/123456789 <https://serviceprovider.com/entitlements/123456789>
</saml:AttributeValue>
</RequestedAttribute>

I am using this code (buildSAMLObject is from the Book). I see (in the last for loop) the values in there, : 

List<RequestedAttribute> raq = x.getRequestedAttributes().stream().map(z -> {
                        RequestedAttribute ra;
                        try {
                            ra = OpenSAML330LHelper.buildSAMLObject(RequestedAttribute.class);
                            ra.setName(z.getName());
                            ra.setNameFormat(z.getNameFormat());
                            ra.setFriendlyName(z.getFriendlyName());
                            ra.setIsRequired(z.isRequired());

                            List<AttributeValue> attrVal = z.getAttributeValues();
                            if (attrVal != null) {
                                List<XSString> back = attrVal.stream().map(y -> {
                                    try {
                                        XSStringBuilder stringBuilder = (XSStringBuilder) XMLObjectProviderRegistrySupport.getBuilderFactory()
                                                .getBuilder(XSString.TYPE_NAME);

                                        XSString stringVal = stringBuilder
                                                .buildObject(org.opensaml.saml.saml2.core.AttributeValue.DEFAULT_ELEMENT_NAME, XSString.TYPE_NAME);
                                        stringVal.setValue(y.getAttributeValue());
                                        return stringVal;
                                    } catch (Exception e) {
                                        throw new IllegalStateException(e);
                                    }
                                }).collect(Collectors.toList());
                                ra.getAttributeValues().addAll(back);
                            }
                            return ra;

                        } catch (OpenSAMLUtilitiesError e) {
                            throw new IllegalStateException(e);

                        }

                    }).collect(Collectors.toList());

                    for (int i = 0; i < raq.size(); i++) {
                        acs.getRequestAttributes().add(raq.get(i));
                    }

The output is without any attribute value over the Requested Attribute. Am I doing some stupid thing here? 

 <md:AttributeConsumingService index="0" isDefault="true">
                <md:ServiceName>Service Name</md:ServiceName>
                <md:ServiceDescription>Service Description</md:ServiceDescription>
                <md:RequestedAttribute FriendlyName="XSPA Purpose Of Use" Name="urn:oasis:names:tc:xspa:1.0:subject:purposeofuse" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" isRequired="true"/>
                <md:RequestedAttribute FriendlyName="XSPA Role" Name="urn:oasis:names:tc:xacml:2.0:subject:role" NameFormat="urn:oasis:names:tc:SAML:2.0:attrname-format:uri" isRequired="true"/>
            </md:AttributeConsumingService>
