Community Auth require_role

The require_role method doesn't seem to be working for me.  It logins in someone with admin role but it doesn't give access to the managers role. 

in controller

PHP Code:

public function reg_users()
    {
        if( $this->require_role('admin,managers') )
        { 


I also tried to use the require_min_level(6) instead of the require_role() method but it doesn't work either it just lets in the admin role.  I've also tried require_role('managers') and no go there either.

in authentication.php

PHP Code:

$config['levels_and_roles'] = array(
    "1" => "noaccess",
    "6" => "managers",
    "9" => "admin"
); 


I'm not sure whats going on.
