> Once upon a time, when we were authenticating users, we were fetching the password from
the backend, which was costly, beside checking that the entry existed (another lookup done
on the backend).
> The idea was to add a credential cache to avoid doing that repetitively.
> The thing is that it's not anymore necessary because before doing any kind of password
verification, we fetch the entire entry, including its password.
> Still, we have kept the credential cache.
> We can now remove it, which will incidentally remove a contention point (and the necessity
of invalidating the cache when the entry was moved, renamed, or its password removed or modified).
> An extra benefit is that we won't have a place in memory where the password will be stored
for a long period of time...
