Sun Java System Calendar Server 6.3 Administration Guide

10.1 Overview of Multiple Domains in Calendar Server Version 6.3

Calendar Server 6.3 features multiple domains as the default, and only, way to organize your user and group LDAP entries. That is, you must have at least one domain under the root node and all of your user and group entries must reside under a domain node. In earlier versions of Calendar Server, the use of domains to contain user and group entries was optional. You could run Calendar Server without using domains at all. That is no longer true for Calendar Server 6.3; you must have at least one (default) domain.

In a multiple domain environment, each domain shares the same instance of the Calendar Server system, which allows multiple domains to exist on a single server. Each domain defines a name space within which all users, groups, and resources are unique. Each domain also has a set of attributes and preferences that you specifically set. All user and calendar IDs for domains must be fully qualified.

The configuration program asks you for the necessary information to set up the default domain. When the configuration program is done and you have created all of the domains you need, before copying your user and group LDAP entries to the desired domains, you must prepare the user and group entries by running the migration utilities to convert your non-domain user and group LDAP entries to domain ready user and group entries. The utilities to run are csmig and csvdmig.

If you are upgrading to Calendar Server 6.3 from a non-domain version of Calendar Server, you have several choices to make:

If you had hosted (multiple) domains set up prior to upgrading to the current version, your user IDs and calendar IDs need not be altered. However, there are some new ics.conf parameters that need to be configured, as shown in the following section:10.4 Additional Parameters Required for Multiple Domain Mode in Calendar Server Version 6.3.


Caution – Caution –

If your site is currently configured for multiple instances of Calendar Server on a single machine, or if you have implemented a limited virtual domain mode, contact your Sun Microsystems sales account representative for an evaluation of your migration requirements.
