OpenLDAP and Google Cloud Directory Sync

[Brian Hill <bchill@bch.net>]

I would like to get OpenLDAP to trigger a GCDS sync whenever either 
certain attributes are modified or even anything the DB, if it isn't 
possible to limit it to certain attributes.

I am thinking along the lines of OpenLDAP calling some external program 
after a modification, but if there is another way to do this that I am 
missing,  I am all ears. I have looked at the various overlays but none 
seem relevant.

Has anyone done this or have general suggestions?
