syncrepl refreshAdnPersist
Hello -
I'm trying to implement an OpenLDAP infrastructure with one Master
Server supporting 4 databases and two Shadow Servers using syncrepl
replication. I'm using OpenLDAP 2.4.11 and Berkeley DB 4.6.21 as
backend DB. Configuration looks like this:
Master:
#US database
database bdb
suffix "c=US"
rootdn "cn=admin,c=US"
rootpw ****
directory /var/lib/ldap/US
checkpoint 1024 5
index objectClass eq
index mail,cn,ou,o,c eq,pres,sub
index serialNumber eq
index uid eq
index entryUUID eq
index entryCSN eq
overlay syncprov
syncprov-checkpoint 10 5
syncprov-sessionlog 200
#GB database
database bdb
suffix "c=GB"
rootdn "cn=admin,c=GB"
rootpw *******
directory /var/lib/ldap/GB
checkpoint 1024 5
index objectClass eq
index mail,cn,ou,o,c eq,pres,sub
index serialNumber eq
index uid eq
index entryUUID eq
index entryCSN eq
overlay syncprov
syncprov-checkpoint 10 5
syncprov-sessionlog 200
database bdb
suffix "c=JP"
rootdn "cn=admin,c=JP"
rootpw ********
directory /var/lib/ldap/JP
checkpoint 1024 5
index objectClass eq
index mail,cn,ou,o,c eq,pres,sub
index serialNumber eq
index uid eq
index entryUUID eq
index entryCSN eq
overlay syncprov
syncprov-checkpoint 10 5
syncprov-sessionlog 200
#Corp database
database bdb
suffix "o=My Company."
rootdn "cn=admin, o=My Company."
rootpw *******
directory /var/lib/ldap/dst
checkpoint 1024 5

US Database has approximately 100000 records and GB Database has
approximately 70000 records. After a month of piloting this
infrastructure I noticed that shadows are missing about 10 records for
US and GB database. Any idea what is wrong with this configuration and
why not all records get populated from Master to Shadows?
Thanks.
