I think the first thing I'd check is why you'd have more than one row being
returned. Is this a problem with some other part of the system? Bad data
import? Not checking for unique users when creating them? Something
like that.
If you do everything you can to prevent the possibility of multiple users,
then you can still check for multiple results if you want, maybe send an
email to yourself, but for the sake of not frustrating your users, just
take the first result and compare the login to that. The worst that'll
happen is they won't match and the user won't get logged in. Best case is
they get logged in and you won't get an annoyed user calling you.
