A common mistake is failing to add the site permissions for staff users. If a user doesn't have permissions for any site, they will not be able to log in.
This was discussed in a recent thread and a patch was added to the development version of mezzanine to warn users when they're about to create a staff user that cannot log in (usually not desirable). -- You received this message because you are subscribed to the Google Groups "Mezzanine Users" group.
