Hi!

We are using ADFS as the SAML idp for our applications. For some reasons we need ADFS to reply using a redirect binging, not a post binding.

We have set picketlink.xml like this:

  <PicketLinkSP xmlns="urn:picketlink:identity-federation:config:2.1" BindingType="REDIRECT">

This has caused our application to use redirect when it calls the IdP but has not changed the binding element in the request. SAML requests looks like this:

<?xml version="1.0" encoding="UTF-8"?>

<saml2p:AuthnRequest

    AssertionConsumerServiceURL="application url"

    Destination="adfs url" ForceAuthn="false"

    ID="_1499958212546_eaa8b869b80e78aaf86d5be01395f502" IsPassive="false"

    IssueInstant="2017-07-13T15:03:32.546Z"

    ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-POST" Version="2.0"

    xmlns:saml2p="urn:oasis:names:tc:SAML:2.0:protocol">

    <saml2:Issuer xmlns:saml2="urn:oasis:names:tc:SAML:2.0:assertion"sp id</saml2:Issuer><saml2p:NameIDPolicy AllowCreate="true" Format="urn:oasis:names:tc:SAML:2.0:nameid-format:transient"/></saml2p:AuthnRequest>

And would like the ProtocolBinding to be like this:

    ProtocolBinding="urn:oasis:names:tc:SAML:2.0:bindings:HTTP-REDIRECT" Version="2.0"

How can we achieve this?
