What I had in mind was to try to get an idea of what would be involved 
in a migration strategy to move from fragmented directory services on
different platforms to an enterprise directory that included firewalls
as follows:

Banyan Vines   }    LDAP
Novel Netware  }   access         Packet    Proxy  Choke
Lotus Notes    }--enterprise--|--filtering--fire--filtering--|--Internet
Assorted Unix's}  directory   |   router    wall   router    |
Windows Nt     }              |                              |
                           Packet                         External
                          filtering                       hardend
                           router                         DNS server
                              |             
                          Packet filtering--Corporate  
                          firewall          Intranet

This is essentially a split DNS to hide the corporate network.  The
external DNS would provide minimal DNS information on a skeletonized
Unix box, while the internal LDAP access enterprise directory would
provide directory information for everything.
