OpenLDAP, replication.

Hi

I have two openldap servers. I am trying to get the master one to replicate. Here are my slapd.conf files:

Master slapd.conf

# This is the main slapd configuration file. See slapd.conf(5) for more
# info on the configuration options.

updateref ldap://192.168.206.129:389

The two servers are working. They are with empty databases. I can add records to both of them. There are no errors in the replication log file, but still, there is nothing on the slave server. If you need something else, tell me.

Regards.

Re: OpenLDAP, replication.

The first thing that comes to mind is not specific to LDAP...Are you allowing connection via /etc/hosts.allow ?  Or have you done anything with IPTables ?  Can the each server connect to the other on port 389 ?
If that isn't the issue, have you read the Replication docs for OpenLDAP ?
