Well, the only solution then would be to add some weasel words like
"perhaps expired password", but that seems so rare that I doubt it would
apply very often and seems like an odd suggestion.   We could go with:

        password authentication failed for user \"%s\": perhaps invalid or 
expired password

We did have two threads on this issue in the past 12 months so I figured
we should try to do something.
