About the Configuration Directory Server

At time of installation, Netscape Messaging Server 4.1 requires that a configuration directory server be available to it, because during the installation, Netscape Messaging Server 4.1 contacts the configuration directory server and populates it with configuration information. After initial installation, Netscape Messaging Server 4.1 copies the configuration data back to its local cache, after which the external configuration directory server is no longer strictly relied upon. If the configuration directory server becomes unavailable, Netscape Messaging Server 4.1 will emit warning messages stating that it is starting up with configuration data from its own local cache. These messages are expected and harmless.

If you choose to install the Netscape Directory Server to serve Netscape Messaging Server 4.1, you can make it highly available by also installing and configuring Sun Cluster HA for Netscape LDAP. For more information about Sun Cluster HA for Netscape LDAP, see the Sun Cluster 2.2 Software Installation Guide.
