Mixed insecure and secure (unpatched/patched) DCs are not supported
after the Nov 2021 security updates.
However, we do our best to stay secure provided there was a normal PAC,
we use the SID found there in the main LOGON_INFO.
The warning you see seems to come from the constrained delegation code,
so perhaps your application is using that.
Microsoft intends to do strictly require patched DCs, and has a
registry key that can be set to enforce that now, but keeps putting off
the deadline for strict enforcement.
The security issues we fixed are serious, I would strongly recommend
getting onto patched versions urgently.
