What we can do is halfway, if an overlay view is activate for an AD
domain then in IPA we have options to automatically generate IDs for any
AD user (if the admin wants), these IDs get stored in the Ad overlaying
view.

Note that we have to do this anyway if you want to allow also legacy
clients to see the same ids, so it seem to me the best/only possible
way.

The only caveat is that it requires some development on the IPA side to
do this object creation, but it is not a lot of code as we can reuse DNA
for the actual ID allocation, we just need to create the entry in the
view.

Simo.
