Ok, but we should mention this somewhere like in the admin guide perhaps.

Eh, I'm not sure it should be in the man page.  The point is, if you ever 
want guaranteed atomic writes, you have to use slapo-accesslog to serialize 
them.  That's an issue that affects other LDAP servers as well.

AS Pierangelo said:

There is no guarantee of DSA-wide or even database-wide atomicity in write 
operations, including internal ones.  This was never even intended to be in 
place.  This is a known design limitation not only of slapo-unique, but 
also of slapd (and, I'd say, of LDAP itself).
