H1: The Big Picture - Configuration Choices
This section gives a brief overview of various {{TERM:LDAP}} directory
-configurations, and how your stand-alone LDAP server {{slapd}}(8)
+configurations, and how your Standalone LDAP Daemon {{slapd}}(8)
fits in with the rest of the world.
H2: Local Directory Service
-In this configuration, you run a {{slapd}} which provides directory
-service for your local domain only. It does not interact with other
-directory servers in any way. This configuration is shown in Figure 3.1.

H2: Local Directory Service with Referrals
-In this configuration, you run a slapd which provides directory service
-for your local domain and configure it to return referrals to a
-{{superior}} service capable of handling requests outside your local domain.
-You may run this service yourself or use one provided to you.

H2: Replicated Directory Service
-The slurpd daemon is used to propagate changes from a master slapd
-to one or more slave slapds. An example master-slave configuration
-is shown in figure 3.3.
+slapd(8) includes support for {{LDAP Sync}}-based replication, called
+{{syncrepl}}, which may be used to maintain shadow copies of directory
+information on multiple directory servers. In its most basic
+configuration, the {{master}} is a syncrepl provider and one or more
+{{slave}} (or {{shadow}}) are syncrepl consumers. An example
+master-slave configuration is shown in figure 3.3. Multi-Master
+configurations are also supported.

-two configurations in situations where a single slapd does not
-provide the required reliability or availability.
