Drupal generally treats the username in a case-insensitive manner, and this module probably should to. It should just be a matter of applying the SQL function "lower" to both the database field and the argument, like this:

SELECT COUNT(*) FROM {users} u WHERE lower(u.name) = lower('%s')

A backport to 5.x would be appreciated, we're still on that platform.

Thanks!
