Topology suffixes store the data that is replicated. IdM supports two types of topology suffixes: domain and ca. Each suffix represents a separate server, a separate replication topology.
When a replication agreement is configured, it joins two topology suffixes of the same type on two different servers.
- The
domainsuffix: dc=example,dc=com The
domainsuffix contains all domain-related data.When two replicas have a replication agreement between their
domainsuffixes, they share directory data, such as users, groups, and policies.- The
casuffix: o=ipaca The
casuffix contains data for the Certificate System component. It is only present on servers with a certificate authority (CA) installed.When two replicas have a replication agreement between their
casuffixes, they share certificate data.
图 27.2. Topology suffixes
An initial topology replication agreement is set up between two servers by the ipa-replica-install script when installing a new replica.
