Dear all,
 
I have a 4 way Multi-master LDAP synchronization version 2.4.11 configured to run in refreshonly mode, config is below :
 
# syncrepl directives
syncrepl  rid=001
              provider=ldap://ldap01
              bindmethod=simple
              binddn="cn=Manager"
              credentials=xxxxx
              searchbase="o=ABCDE"
              schemachecking=off
              type=refreshOnly
              interval="00:00:00:30"
            attrs="*,+"
              retry="5 5 300 +"
#syncrepl rid=002
#              provider=ldap://ldap02
#              bindmethod=simple
#              binddn="cn=Manager"
#              credentials=xxxxx
#              searchbase="o=ABCDE"
#              schemachecking=off
#              type=refreshOnly
#              interval="00:00:00:30"
#              attrs="*,+"
#              retry="5 5 300 +"
syncrepl rid=003
              provider=ldap://ldap03
              bindmethod=simple
              binddn="cn=Manager"
              credentials=xxxxx
              searchbase="o=ABCDE"
              schemachecking=off
              type=refreshOnly
              interval="00:00:00:30"
              attrs="*,+"
              retry="5 5 300 +"
syncrepl rid=004
              provider=ldap://ldap04
              bindmethod=simple
              binddn="cn=Manager"
              credentials=xxxxx
              searchbase="o=ABCDE"
              schemachecking=off
              type=refreshOnly
              interval="00:00:00:30"
              attrs="*,+"
              retry="5 5 300 +"

 
#overlay syncprov
syncprov-checkpoint 100 10
syncprov-sessionlog 100
# Performance tuning directives
sizelimit       5000
threads         16
idletimeout     0
cachesize       10000
checkpoint      256     15
 
We will do add/modify/delete operation daily and I have a script to check record by record of the sync status.  From time to time, there is some records deleted in one of the LDAP server will not be replicated to the other servers occasionaly.  But it will eventually deleted after long random time. (may be 1-2 days)
 
Any idea ?
 
Thanks
