Another goal for OpenLDAP 2 3 was enhanced stability, particularly in regard to replication The Content Synchronization replication mechanism (aka syncrepl) was introduced in OpenLDAP 2 2 and promised to provide easier to manage replication than the slurpd mechanism inherited from the UMich release, but the implementation in OpenLDAP
LDAP Sync Replication Allows clients to maintain copies of LDAP tree fragments OpenLDAP implementation called syncrepl In process of becoming a standard - see The LDAP Content Synchronization Operation Internet Draft by Kurt Zeilenga Provides stateful replication with both push and pull based sync SAGE-AU Conf 2006 – p 17

HP Directory Services (cont'd) • Enterprise Directory (ED) – Sun ONE • Active Directory (AD) – Microsoft Active Directory • Extranet Directory (XD) – OpenLDAP (actually still Sun ONE – cutover date is Friday, 13th August) • Domain Specific Directories – OpenLDAP mainly, some Sun ONE • “OpenLDAP” is the Symas Connexitor
Why not use the legacy OpenLDAP Back-end A “real” back-end – LDAP traffic goes through Samba, to make sure all the AD request processing specifics are implemented Incompatible with replication, as back then there was no transaction support Support was discontinued, since then Samba has made huge progress – Multi-master replication
flexible directory multi master replication and cluster technology • Integrated, multilevel system security with integrated Directory and Database Security • Directory Integration with Microsoft Active Directory, Sun, Novell, eDirectory, and OpenLDAP • Integration with Oracle E-Business Suite, Siebel, Peoplesoft • Standards based, LDAP v2
Openldap Subschemasubentry An LDAP server MUST provide information about itself and other information subschemaSubentry: subschema entries (or subentries) known by this server Note that this works on Active Directory and OpenLDAP (using System Base, "subschemasubentry" ), var searchResponse = (SearchResponse)
• OID, Active Directory, and OpenLDAP are all just three out of many possible LDAP Directory Servers software products • Oracle “Connect Descriptors” can be stored and accessed from any LDAP Directory Server • Active Directory and OpenLDAP are the easiest to setup

Provider Configuration - Replication User
Both replication strategies will need a replication user, as well as updates to the ACLs and limits regarding this user. To create the replication user, save the following contents to a file called replicator.ldif: Then add it with ldapadd: Now set a password for it with ldappasswd: The next step is to give this replication user the correct privile...
Provider Configuration - Standard Replication
The remaining configuration for the provider using standard replication is to add the syncprov overlay on top of the dc=example,dc=comdatabase. Create a file called provider_simple_sync.ldifwith this content: Add the new content: The Provider is now configured.
Consumer Configuration - Standard Replication
Install the software by going through the installation steps. Make sure schemas and the database suffix are the same, and enable TLS. Create an LDIF file with the following contents and name it consumer_simple_sync.ldif: Ensure the following attributes have the correct values: 1. provider: Provider server’s hostname – ldap01.example.comin this exam...
Provider Configuration - Delta Replication
The remaining provider configuration for delta replication is: 1. Create a new database called accesslog 2. Add the syncprov overlay on top of the accesslog and dc=example,dc=comdatabases 3. Add the accesslog overlay on top of the dc=example,dc=comdatabase
Consumer Configuration
Install the software by going through the installation steps. Make sure schemas and the database suffix are the same, and enable TLS. Create an LDIF file with the following contents and name it consumer_sync.ldif: Ensure the following attributes have the correct values: 1. provider: Provider server’s hostname – ldap01.example.comin this example – o...
Testing
Once replication starts, you can monitor it by running: On both the provider and the consumer. Once the contextCSNvalue for both match, both trees are in sync. Every time a change is done in the provider, this value will change and so should the one in the consumer(s). If your connection is slow and/or your LDAP database large, it might take a whil...
What is a replicated directory in OpenLDAP?
Replicated directories are a fundamental requirement for delivering a resilient enterprise deployment. OpenLDAPhas various configuration options for creating a replicated directory. In previous releases, replication was discussed in terms of a masterserver and some number of slaveservers.
How does LDAP replication work?
This is done through LDAP replication. Replication is achieved via the Sync replication engine, syncrepl. This allows changes to be synchronised using a Consumer - Provider model. A detailed description of this replication mechanism can be found in the OpenLDAP administrator’s guide and in its defining RFC 4533.
Can OpenLDAP multi-master replication be split-brain?
OpenLDAP Multi-Master Replication is for high availability, not load balancing. If a split-brain is possible, consider the mirror mode architecture described in the OpenLDAP Administrator’s Guide. A split-brain is where two or more nodes of a cluster are operating independently, which can cause the cluster data to become corrupt or out of sync.
What is LDAP syncrepl?
18.1.1. LDAP Sync Replication The LDAP SyncReplication engine, syncreplfor short, is a consumer-side replication engine that enables the consumer LDAPserver to maintain a shadow copy of a DITfragment. A syncrepl engine resides at the consumer and executes as one of the slapd(8) threads.
