Hi,
Is there a way to force the replication between Master and the slave?. The number of
objects and entries are the same in both master and slave,however the some fields don`t
have the same content (eg : last login time)Wondering if there is way to keep both in sync
in terms of content and objects/entries.
Cheers

I have a strange problem,the replication between master and slave is functioning
well,however I do see difference in number of objects.Why is that?
Master# ldapsearch -x -b 'o=abc.com' '(objectclass=*)' | egrep "
numResponses|numEntries"
# numResponses: 38861
# numEntries: 38860
Slave# ldapsearch -x -b 'o=abc.com' '(objectclass=*)' | egrep "
numResponses|numEntries"
# numResponses: 38857
# numEntries: 38856
Cheers

Did you compare the contextCSN attributes on the servers when you compared the
number of entries ? Comparing the contents is only valid if the servers think
they are in sync ...

I don`t find any contextCSN,we are not using the syncrepl instead the replication
parameters are configured in slapd.conf.
Master
replica uri=ldap://slave:389
binddn="cn=Replicator,o=abc.com"
bindmethod=simple
credentials=simple
replogfile /var/lib/ldap/openldap-master-replog
Slave
updatedn "cn=Replicator,o=abc.com"
updateref ldap://master:389
access to * by dn="cn=Replicator,o=abc.com" =rw
by * read
The ldiff files (from slapcat) are not the same in size on matser and slave.
Cheers

With slurpd, failures can occur, and depending on the reason for the failure,
replication will not fix itself. You should either monitor the reject files
and the status files sluprd generates, or switch to syncrepl (which will allow
you to monitor replication status, and in many failure scenarios replication
will catch up).

So the only option to sync... would be to push the slapcat from the master(ldiff file) and
load it into the slave.

Have you done a slapcat of each, and compared the resulting LDIF?
