If you are using ldbm, there are no guarantees of anything. If you are using 
bdb on OpenLDAP 2.2 and you don't run database recovery after a reboot (or 
unclean shutdown of slapd) and before starting slapd, you could lose some 
data (as slapd in 2.2 doesn't do automatic database recovery, the operations 
in the transaction logs could be lost). The fix for this is to ensure the 
init script runs database recovery before starting slapd, or upgrading to 
2.3.

But, this is why it would have been useful if you provided at least *some* 
information on what version your are using, and what backend.
