Actually it does not sound similar, since that just modifies incoming
update operations while you need to spawn multiple search-and-updates:

Look at how the refint overlay handles modrdn operations.  They trigger
a search for other entries to modify or delete.

Not sure what "with respect to previous password hash" means, if not
EXOP_MODIFY_PASSWD.  That's exactly what it does.  You just need an
overlay in addition, to spawn updates to other entires.  And if you want
to catch add and modify operations too, the overlay can do that as well.

Or do you mean: If you update uid=foo,ou=bar with password X and the
overlay also finds uid=foo,ou=baz with another password Y, should then
the other password be updated as well?  Don't know but I guess you just
duplicate the operation of the modify password exop with the old
password.  Note that if you read the password to verify, you may run
into access control rules that just allow minimal access: write and
auth.
