Case insensitive logins¶ ↑

If your database schema doesn’t support case insensitive logins, you can tell Rodauth to automatically lowercase login param values during authentication and persistence via the normalize_login configuration option:

normalize_login(&:downcase)

Of the four database types Rodauth officially supports (PostgreSQL, MySQL, Microsoft SQL Server, and SQLite), only SQLite does not support a case insensitive column for storing logins by default. However, other databases could be configured to not use a case insensitive column for logins by default, in which case you would want to use this setting.
