No
IMHO, this is a bad idea..If you need transactions, you probably need a
RDBMS..
Lack of transactions participates to better performance for the
directory than a transactional RDBMS for read intensive applications.. 

Despite this, I've heard about a LDAPv3 extension for transactional LDAP
.. But don't have any resources..

Maybe it can be simulated if there is only one way (a gateway) to update
the directory.. So you could emulate a optimistic locking system, or
implements a 2 Phase Commit.. But if you have multiples sources of
update, it's becoming much more complex .. :-(

Best regards, Stéphane
