[Zope] Security Guru Question

[Alan Runyan]

Hi.

I am finished my application but have one last stumbling block.
Its inside of AccessControl/Role.py in get_valid_userids()

I have a object herirachy like:

Zope Root -> MyApp -> Company -> Business Units

in My App I have a PsycoPG connection object call my_users
and in all Companies I have a exUserFolder.  

now when I goto a Company or Business Unit and try to
assign/edit/list Local roles it bombs.  Because exUserFolder
cant find the 'my_users' connection object.  Why?  Well
I know why.. 

because when the xxxLocalRoles screens are called they
call get_valid_userids which at the top says:
aclu = getattr(aq_base(item), 'acl_users', _notfound)

and immediately aclu has all acquisition wrappers peeled off
of it and now I can not go any further up the heirarchy than
Company.  

I am very tempted in taking the aq_base(item) part off..and
I believe all will work... But I really need someone who
understands the implications of this to say whats the best
way forward.  I was thinking about overriding this method
in my Company/Business Unit classes with a version that
doesnt have aq_base().

I have no other acl_user folder objects except for in the root
of the system.  I could have one in My Application but its 
not necessary.

thanks in advance,
