- The administrator's password form took "password-based
authentication: Disabled" with "must change it at the next login":
the change form asks for the old password, which the user then never
had, so they could not get past it. That combination is refused, and
an administrator cannot disable their own password.
- A user who must change the password could still use the API with
their tokens. A token is now refused until they change it, as the
pages are.
The API Tokens tab gets a "Last used" column, so an unused token can be
told from one a script still needs. The token's last use is written when
it authenticates, at most once a minute (accounts.auth.TokenAuthentication,
knox's class with that one addition; the API schema describes it as
knox's).
A user has at most ten tokens; a new one is refused until one is
deleted. Expired tokens do not count, and are deleted when a new token is
made.
