    Hi, list.

    I'm trying to implement syncrepl in my openldap 2.3.35 without
sucess. I tryed many (I sed: MANY) times to slacat, slapadd to slave for
syn ldap servers, but for some reason with I don't know, the slave lost
the sync.

    Then I have to do the same thing ate night:

- stop ldap master;
- slapcat master
- slapadd on the slave;
- start master and start slave

Hi Jeronimo,

With syncrepl, you don't need to do a 'slapcat' on the master and
'slapadd' on the slave. Just start the master, then the slave. You
will see the slave doing a full sync.

His point is that replication works for a while, and then stops. After which the only way he can get it going again is to slapcat the master and reload the slaves. I.e., replication works for a while, and stops. Restarting the slave, IIRC, does not restart replication. (I've discussed this some with him on the #ldap channel on IRC).

This works about one hour, in the morning wasn't syncing again. If i restart the slave ldap, then the changes on the master is replicated, but stops to sync "on line" after this.

What do you see in your ldap logs? Are your master and slave in two different subnets separated by a firewall?

Restarting the replica I would think would re-establish any connection and queue replication to start again, which doesn't seem to be happening.
