Metadata Attributes for MFA retrieval in mfa-authn-config.xml script

Hi all,

IdP 4.3.1

I’m trying to move to using metadata attributes to control which SP’s require MFA instead of currently hard coding in mfa-authn-config.xml

The following are the 2 attributes that I’m using and the MFA flow works for both.

       <saml:Attribute Name=

      <saml:Attribute Name=

What I need to do is determine which value is passed into the MFA process and then test the users group membership for the StaffOnly value.
The group membership test is working.
We have some sites where staff require MFA but students don’t.

I’m unable to work out what I need to query to return the value “”
I've tried
           authnRequestedPrincipalContext = Java.type("net.shibboleth.idp.authn.context.RequestedPrincipalContext");
but its not returning the values that I need.

My Javadoc foo is very basic basic .

Can someone point me in the right direction.
