[Zope] Why is acl_users "Contents" hidden?

[Kyler B. Laird]

I've been planning on using roles to control
access to folders.  Unfortunately, I find that
if a user doesn't have the "Manage" role, 
requests to acl_users/manage_workspace will
get redirected to acl_users/manage_access and
no "Contents" tab will be shown.

The user can still go to acl_users/manage_main
and manage users, but he must know how to get
there.  Is there a simple fix?

Thanks.
