What happened?

Steps to reproduce:

1. attempt to create a user ("test_user"). This will fail with a generic error message: "Failed to create new User: test_user".
2. change "test_user" to "test-user" and try again. This will succeed.

If underscores are not allowed as part of usernames (i.e. this is by design), then the error message should be more descriptive or, better, a tool tip on the username field should prompt that underscores are disallowed.

If underscores are intended to be allowed, then this is a bug in the user creation process.
