issue with acl9 plugin

I am trying to allow users with role "corporate" to access their own company. Currently a user with that role gets blocked.

If i login as admin or change the access control to allow all, it works fine. The issue is pertaining to Corporate user role having a company.

here is all the code http://pastie.org/672733

User controller

class UsersController < ApplicationController
  # GET /users
  # GET /users.xml

  before_filter :load_user_index, :only => ['index' ]
    access_control do
      allow :admin
    end

  before_filter :load_user, :only => ['show', 'destroy', 'edit' ]
    access_control do
      allow :admin
    end

  before_filter :load_user_manage, :only => [ 'create', 'new', 'update', 'destroy' ]
    access_control do
      allow :admin
    end
