Yes, it is.

This whole concept of the auth APIs goes back to the days of HC 2.0 and
it remained virtually unchanged in HC 3.x and HC 4.x. The auth APIs were
primarily designed to work well with standard auth schemes like BASIC
and DIGEST and similar password based auth schemes. Things like Kerberos
and native Windows auth were not properly factored it at that point of
time. We can think of a better abstraction for HC 5, but for now we will
have to live with what we have.
