Java Desktop System Conguration Manager Release 1.1 Installation Guide
CHAPTER
1
Introduction
Provides a brief introduction about the JavaDesktop System Conguration Manager, Release 1.1.
Introduction
The JavaDesktop System Conguration Manager, Release 1.1 is aimed at providing a central conguration for desktop hosts running the JavaDesktop System. Settings can be assigned to various elements of an organization structure, enabling the administrator to manage groups of users or hosts in a simple way. Its main components are:
An LDAP server containing the organizational structure of users and hosts to be managed, which will hold the conguration data, A web-based management tool allowing administrators to dene and assign conguration data to elements of that organizational structure, Desktop components installed on the client host, which retrieve the conguration data on behalf of the currently logged in user and expose it to the various applications making up the Java Desktop System.
The management tool is a web-based application run within the Java Web Console. It allows the administrator to browse the organization structure of the LDAP server and assign policies to its elements. The policies are displayed and edited according to policy templates, which dene the settings that the management tool will be manipulating.
The desktop components are organized around the JavaDesktop System Conguration Agent, which retrieves conguration data from the LDAP server on behalf of users and makes it available to a number of conguration system adapters, which complement the local conguration (default settings provided by applications

and user settings) with the policy settings. Currently supported conguration systems are GConf (which handles the conguration of Gnome applications such as the Gnome desktop or Evolution), MozillaPreferences and StarRegistry (StarOffices conguration system).

CHAPTER
2
LDAP
Server
This chapter provides information about setting up and deploying an LDAP server for use with the Conguration Manager.
Concepts
Within the Java Desktop System Conguration Manager framework, conguration data are associated with entities, which are entries in the LDAP repository and correspond to elements of the organizational structure of the company.
The recognized entities are:
Organization: typically represents either an organizational (divisions, group, teams) or geographical (continent, country, site) unit of the overall hierarchy. User: represents a leaf node of the overall hierarchy and, as the name implies, usually a user. represents a logical structuring unit for the network organization.Domain: Host: also represents a leaf node of the overall hierarchy but points to a machine on the network. usually a distinction in terms of functionRole: represents properties, (administrator, site management), applied to a set of users.
The organization and user entities are used to dene a user tree, while the domain and host entities dene a host tree. These two trees are independent but are manipulated in a similar way in the framework.
The relationship of organization and domain entities with other entries is dened by the physical location of the entries within the repository. That is, the organization and domain entities can include any entry that is located below these two entities in the tree. The relationship of roles to users or hosts is dened by the attributes of the user and host entries.
