We currently have a single OpenLDAP server using the cn=config backend. We'd like to add a second OpenLDAP server and configure them for multimaster replication. What do we need to do to
- enable replication on the existing server and
- initialize the new server with the existing data
So far what I've done (following this guide) is:
Syncing configuration
dn: cn=config changetype: modify replace: olcServerID olcServerID: 1 ldap://foo.example.com olcServerID: 2 ldap://bar.example.com - replace: olcSaslSecProps olcSaslSecProps: noanonymous dn: cn=module,cn=config changetype: modify olcModuleLoad: syncprov dn: olcDatabase=config,cn=config changetype: modify olcRootDN: cn=admin,cn=config olcRootPW: abc123 add: olcSyncRepl olcSyncRepl: rid=001 provider=ldap://foo.example.com bindmethod=simple binddn="cn=admin,cn=config" credentials=abc123 searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=3 olcSyncRepl: rid=002 provider=ldap://bar.example.com bindmethod=simple binddn="cn=admin,cn=config" credentials=abc123 searchbase="cn=config" type=refreshAndPersist retry="5 5 300 5" timeout=3 - add: olcMirrorMode olcMirrorMode: TRUE dn: olcOverlay=syncprov, olcDatabase=config, cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: syncprov
This got configuration syncing working on both directions.
Syncing data
dn: olcDatabase=bdb,cn=config changetype: modify add: olcMirrorMode olcMirrorMode: TRUE - add: olcSyncrepl olcSyncrepl: rid=001 provider=ldap://foo.example.com searchbase=dc=example,dc=com binddn="uid=ldapsync,ou=Special Accounts,dc=example,dc=com" credentials=xyz123 olcSyncrepl: rid=002 provider=ldap://bar.example.com searchbase=dc=example,dc=com binddn="uid=ldapsync,ou=Special Accounts,dc=example,dc=com" credentials=xyz123 dn: olcOverlay=syncprov, olcDatabase=bdb, cn=config changetype: add objectClass: olcOverlayConfig objectClass: olcSyncProvConfig olcOverlay: syncprov
I verified that these changes were synced to the second server, and that the ldapsync user can authenticate and can see all the data it needs to. However, the bdb data doesn't seem to be syncing in either direction. What am I missing?
