Full_Name: Pawan Kumar Version: openldap-2.3.32 OS: CentOS release 4.5 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (14.140.116.135) Hi, We are using openldap-2.3.32 on CentOS release 4.5(2.6.9-89.0.25.ELsmp). We have master-slave setup and we have two secondary ldap servers on which we are only replicating the one of our OU. We are not able see the contextCSN on secondary ldap servers. we are using the syncreplca(delta sync replication using accesslog. Below are the secondary slapd.conf replication section. syncrepl rid=111 provider=ldap://masterldapserver type=refreshAndPersist retry="60 10 300 +" searchbase="ou=people,dc=example,dc=co,dc=in" schemachecking=off bindmethod=simple binddn="cn=Manager,dc=example,dc=co,dc=in" credentials=password logbase="cn=accesslog" logfilter="(&(objectClass=auditWriteObject)(reqResult=0))" syncdata=accesslog And how we can monitor ldap replication in that case where we are replicating only one OU from master ldap server? any quick response will be appreciated.
