* This class assumes that the identity of a certificate is SPIFFE which is a
URI that is present as part of the SAN
* of the client certificate. It has logic to extract identity (Spiffe) out of
a certificate & knows how to validate

Review Comment:
Looking at `DurationSpec` code, it looks like this isn't easily achievable,
and I think there is precedence in C* for logging in the resolved unit rather
than the given one, so probably ok to remain this way.
