size limit problem in 2.4.10

Hi list. I'm trying to limit queries for one user in my slapd.conf, with this rules:

limits dn.exact="cn=user1,dc=domain,dc=com" size.soft=50 size.hard=50 limits anonymous size.soft=50 size.hard=50 limits users size.soft=50 size.hard=50 sizelimit unlimited

But "user1" isn't limited with this rules. If I set "sizelimit 50", the syncrepl doesn't work, even I set no limit in my syncrepl directive or setting limits for replicator user.

This rules was working fine in openldap 2.3.35 until I upgrade to 2.4.10. :-(

Somebody have tips, mans, or ideias to solve this issue ?

Thanks.
