Same result after correcting the syncrepl configuration (same for ldaps, ldap+starttls, or ldap only). The problem can be simulated consistently by running several copies of perl scripts using Net::LDAP in background on 2 clients. Each of them add/delete 100 users, e.g. running 4 scripts on each client to operate on add/delete of 2-3 sets of 100 users. Thanks again.

Right, I added redundant lines. Will test again after removing them. Thanks for your help.

Hi all, I set up a 2 server multi-master environment using OpenLDAP 2.4.9 + BerkeleyDB 4.6 on CentOS 5.1. Make test and simple load test on add/mod/del are okay. However, seems some records are not replicated in delete phrase when there are lot of simultaneous delete operations (e.g. 10 threads spawned from 2 clients to add/del 100 users in each threads). I'm newbie to syncrepl and have no idea about the problem are scanning debug output. My slapd.conf syncrepl section follows: #master overlay syncprov syncprov-checkpoint 100 10 syncprov-sessionlog 100 #consumer syncrepl rid=001 provider=ldaps://192.168.28.69 starttls=yes tls_reqcert=never tls_cacert=/etc/CA/cacert.pem type=refreshAndPersist retry="5 + 5 +" searchbase="dc=mydomain,dc=hk" schemachecking=off bindmethod=simple binddn="cn=replicator,ou=People,dc=mydomain,dc=edu" credentials=secret

Would anyone pls help? Sorry for the newbie question. Thanks a lot. /st wong

Why are you running StartTSL on an ldaps server?
