I still think that deciding based on error message string is not right,
we may want to have it internationalized and thus hit the same error.
What about returning a custom HTTP header specifying the reason?

Something like that:

X-rejection-reason: password-expired
OR
X-rejection-reason: password-invalid
OR
X-rejection-reason: account-locked

Web UI could customize next actions based on this header instead of
parsing the error message.

If you decide to rather stick with current solution and file my proposal
as an enhancement ticket (or discard it entirely), then ACK.
