Christian,

The olcServerID goes in the cn=config file correct? I will do a ldapmodify to change this.


yes. use the following:

dn: olcDatabase={0}config
changetype: modify
replace: olcServerID
olcServerID: 1 ldap://tntest-ldap-master-1.oreillyauto.com
olcServerID: 2 ldap://tntest-ldap-master-2.oreillyauto.com


The consumer config is what was on there and that's why I asked the question about wiping it out and then using slapcat to put it back in.


slapcat NEVER shows the checksums and protecting comments that you only see when you go looking at the files under slapd.d

  # AUTO-GENERATED FILE - DO NOT EDIT!! Use ldapmodify.
  # CRC32 3411e7fc

Once you have the correct configuration on one server dump it with slapcat -n0 and import it to the second server using slapadd -n0.

Be sure to wipe ALL of the contents in the slapd.d directory before importing with slapadd.

ps: please keep the mailinglist on the Cc: so what we learn from this is for the greater good.

Thanks,
Eric

use slapcat -n0 instead of copying manually the files from the slapd.d directory.

both your entryCSN have #000# for the serverID. Even though it seems you
have somehow modified the configuration.

Your replication cannot work when you have not configured a serverID.

You need at least the following in your configs.

ÂÂ olcServerID: 1 ldap://tntest-ldap-master-1.oreillyauto.com
ÂÂ olcServerID: 2 ldap://tntest-ldap-master-2.oreillyauto.com

Also why does the ModifyTimestamp: attribute from your second server start with a capital 'M'.

Are you still somehow manually poking at the files in slapd.d ?

Please use slapcat / slapadd with the -n0 option to export and import your configuration.
