Use of User/Group Directory

Netscape Messaging Server 4.1 requires use of a user/group directory, which was optional with Netscape Mail 3.5. The user/group directory is an LDAP directory used by the messaging server to process email. You can install and start the messaging server before configuring the user/group directory, but the messaging server depends upon access to the user/group directory after installation. Because of this dependency, the directory server that services the user/group directory should be installed on the multihost disk or on another clustered server, so as to be highly available.

The configuration directory and user/group directory can be serviced by the same directory server instance or by different instances.
