slapd-ldap meta backend and flat ldap migration

[James Saint-Rossy <jsaint-rossy@associates.usss.treas.gov>]

I'm migrating a poorly configured LDAP (flat with no ou's) to one that 
has structure.  My problem is that several of the applications that use 
the LDAP can't handle users/groups in ou's.  I need an temporary 
solution so that I can go ahead with migrating the LDAP, without having 
to wait for the vendors to fix their clients.  I've been playing around 
with slapd-ldap but can't figure out how to do the following.

Here is my structure

O=company,c=us
	ou=sales
	ou=engineers
	ou=admin
	ou=groups

When the user "jdoe" logs on the application tries the following
>BIND dn=""
>SRCH base="o=company,c=us" scope=1 filter="(uid=jdoe)"

User jdoe can be in any of the ou's.  So here are some questions
1.  Is there a way to change the search scope with slapd-ldap?
2.  Can I change the base depending on the filter?
3.  Can I use slapd-ldap to completely flatten the ldap?

Thanks, James.
