Hi,

Please forgive my ignorance if this is a stupid question; I have only been 
messing around with OpenLDAP for a few days, but I believe I hit a roadblock 
that somebody must have seen somewhere.

Basically, I am planning on using a translucent proxy to augment the attribute 
set served up by an external LDAP provider. Specifically I am provisioning 
uidNumber and gidNumbers for AD accounts.  I cannot populate the upstream 
RFC2307 attributes.  My problem is this; it is my understanding that a 
translucent proxy is going to match records in the local and remote databases 
based on DN.  Admins are going to be moving user and group objects around 
upstream, which will reliably break the mapping between local and remote 
databases after the objects with uidNumber and gidNumbers are populated into 
the local database.

I can think of a couple of algorithms that would reconcile this, although they 
would require custom coding and maintaining a localized external view of the 
data (i.e. in a SQL database).   So, I suppose my question is this;

Is there an elegant way to solve this problem, for example, having the 
translucent proxy map by an attribute other than DN, such as an AD SID?

I appreciate your time and input :-)

Thank you,

Dan Sullivan
