My mistake, main problem solved.
Spaces are not allowed in ldap queries. In fact, I didn't get "no result", I got one message "Bad search filter" that was not handled correctly.
I changed my filters so that it now uses the createTimeStamp and modifyTimeStamp attributes. Using "(&(objectClass=groupOfUniqueNames)(modifyTimeStamp<=20091224))", I retrieve the entries that haven't been modified since 2009/12/24.
"modifyTimeStamp" seems like the correct Attribute to query for your use case. "entryCSN" is a bit more than just a timestamp.
Caution : this filter cannot be applied to the entryCSN attribute as it makes OpenLDAP shutdown.
If it did, that would be clearly a bug. You should consider updating to a more recent OpenLDAP release and check if the problem persists there.

Hi,
I'm trying to search entries in an OpenLDAP (v2.4.7) directory using their last modification date as a criteria. Digging in the schemas, I couldn't find an attribute that contained such a value. The only thing I found was the internal attribute "entryCSN" used by OpenLDAP to manage synchronization.
I tried to do several ldapsearch queries, but I couldn't manage to obtain a decent result.
Using "(&(objectClass=groupOfUniqueNames))" => I get every group of the directory. I can see that lots of them were modified in 2009
Related problem :
Using "(&(objectClass=groupOfUniqueNames)(entryCSN<=20091224))" => The slapd2.4 process stops without returning anything.
Using "(&(objectClass=groupOfUniqueNames)(entryCSN <= 20091224))" (The same query with spaces) => I don’t get any result. Shouldn't I retrieve the entries modified before 2010/12/24 ?
Using "(&(objectClass=groupOfUniqueNames)(entryCSN >= 20091224))"
=> I don’t get any result. Shouldn't I retrieve the entries modified after
2010/12/24 ?
Does anyone know how to filter entries using their entryCSN?
Btw, is it even possible?
Best regards
