Hi John,
Nope, this doesn’t work. For both new users and those within my DB I get the generic “WE’RE SORRY, SOMETHING WENT WRONG WHEN ATTEMPTING TO SIGN UP.” error. The logs tell me if I try to signup for an existing user I get the log error of type ‘Failed Signup’ ‘The user already exists.’ But for those users that don’t exist in my DB I get a nice 404 html page returned.
Again, these actions are taken against a custom DB connection with auto-migration enabled.
