Requester/InvalidNameIDPolicy Error with SimpleSAMLPHP SP and ADFS IDP

Question

After looking all over the Internet, particularly

• ADFS 2.0 InvalidNameIDPolcy
• Using SimpleSAMLphp to Authenticate against ADFS 2.0 IdP
• Requester/InvalidNameIDPolicy

I tried all the suggested modifications to authsource.php and metadata php. Nothing worked.

Here is my authsource.php

'default-sp' => array(
    'saml:SP',
    'privatekey' => 'saml.pem',
    'certificate' => 'saml.crt',
    'idp' => 'http://domain.com/adfs/services/trust',

I used the XML to simpleSAMLphp metadata converter to generate the saml20-idp-remote.php

So when I access the page, SimpleSAMLPHP correctly redirects me to the IDP login page. I decoded the SAML Request:

<samlp:AuthnRequest 
    xmlns:samlp="urn:oasis:names:tc:SAML:2.0:protocol" 
    xmlns:saml="urn:oasis:names:tc:SAML:2.0:assertion" 
    ID="_4e03333c7aa76314d965e05f8fcdd3e1f4c5be96c8" 
    Version="2.0" 
    IssueInstant="2014-12-11T19:41:50Z" 
    Destination="https://domain.com/adfs/ls/" 
    AssertionConsumerServiceURL="https://sub.domain.com/simplesaml/module.php/saml/sp/saml2-acs.php/default-sp" 
    ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST">

    <saml:Issuer>
        https://su.bdomain.com/simplesaml/module.php/saml/sp/metadata.php/default-sp
    </saml:Issuer>
    <samlp:NameIDPolicy Format="urn:oasis:names:tc:SAML:2.0:nameid-format:transient" AllowCreate="true"/>

</samlp:AuthnRequest>

After logging in with a valid test account, I'm redirected back to my site with the error.

I tried setting different NameIDPolicy but none of them worked.

    //'NameIDFormat' => 'urn:oasis:names:tc:SAML:1.1:nameid-format:emailAddress',
    //'NameIDPolicy' => 'urn:oasis:names:tc:SAML:2.0:nameid-format:transient',
    //'NameIDPolicy' => 'urn:oasis:names:tc:SAML:2.0:nameid-format:persistent',
    //'NameIDPolicy' => 'urn:oasis:names:tc:SAML:1.1:nameid-format:unspecified',

Thanks!

Yeah. In a fit of anger and frustration. I set NameIDPolicy to null and everything works. FML

'default-sp' => array(
    'saml:SP',
    'privatekey' => 'saml.pem',
    'certificate' => 'saml.crt',
    'idp' => 'http://comain.com/adfs/services/trust',
    'NameIDPolicy' => null,
