| # Because we have some old legacy users in the database, we need to override Devises method for checking if a password is valid. | |
| # We first ask Devise if the password is valid, and if it throws an InvalidHash exception, we know that we're dealing with a | |
| # legacy user, so we check the password against the SHA1 algorithm that was used to hash the password in the old database. | |
