Authentication Context with IDP Federation

I have a question about enabling Authentication Context for CATS 2.0 standards.

I know it is required between CP and RP in case of SP initiated federation sending AuthNContext in SAMLRequest and expecting a response in SAMLResponse.

What about the requirement in IDP initiated federation.

For example, currently CRA and ESDC use identity federation (IDP initiated) without the use of SAML Request. I was wondering if LOA2 Authentication Context is required in this scenario.

Thanks,

Start by reviewing the CATS 2.0 Authentication Context requirements for IDP-initiated federation and comparing them with the CRA and ESDC flows described. Done means the issue records a clear, standards-backed answer about whether LOA2 is required without a SAMLRequest.
