I don't see anything at all here that remotely relates to "Shibboleth
interoperability" or "Shibboleth 2.4.4".
This all seems to be about you injecting HTTP Cookies and ADFS not
reacting to those Cookies as you expect?

(And not that it matters for this issue, but IDP 2.4.4 suffers from
security vulnerabilities and the only supported stable version
currently is 3.3.2:
