When an user, say "DanielLobato" in LDAP gets an account in Foreman, the login is automatically downcased to "daniellobato". This causes issues when external user groups refresh, as we perform a 'where' query on User, using the logins from LDAP to check what users belong in an external user group. So by calling User.where { :name => ['DanielLobato'] } on usergroup.rb, we will get no results and the user 'daniellobato' will be left unsynced.
