Chapter excerpted from Novell's ZENworks Administrator's Handbook by Ron Tanner and Brad Dayley, Novell Press 1999. Excerpt published here by permission from Novell Press.
The process of setting up ZENworks in your NDS tree (or how to fix it if you set things up clumsily) is the subject of much e-mail every month. It's a task that everyone has to do, and if you approach it with a good understanding of how ZENworks affects your tree, you can avoid a lot of confusion and grief later on. We were delighted when Ron and Brad and the friendly editors at Novell Press gave us permission to excerpt this chapter from their new ZENworks Administrator's Handbook, because it offers a first-rate explanation of the various elements of ZENworks, and how they affect your tree design. We think this will answer a lot of the questions we are seeing, particularly from administrators who are new to ZENworks.
This excerpt is the entire Chapter 3, Setting Up ZENworks in Your Tree. This chapter provides a quick overview of the ZENworks system and a high-level view of the changes that will occur within your tree. This will help you understand this system and how it will impact your current Novell Directory Services installations.
The chapter contains sections on:
- Objects in NDS and Impact on the Tree
- Administration Through Novell Administrator
- Novell Client
- Novell Workstation Agents
- Policy Packages and Policies
- Policy Wizard
- Policy Package Wizard
- Setting Up Workstations in the Tree
- Remote Management Rights
Sneak Peek at the first sectionTake a look at what you'll find in the section about the various objects and attributes that are introduced into your tree when the schema is extended.
General ZENworks Architecture
Novell ZENworks requires some changes to your tree structure in addition to extensions to the Novell Administrator (NWAdmin). Additionally, a new client needs to be placed on the workstation with the addition of some agents. This section details the changes that need to occur for you to implement ZENworks into your tree.
Objects in NDS and Impact on the Tree
When you install ZENworks into your tree, not only does it copy the executable files necessary to run the software, it also extends the schema in your tree. The schema extension in your tree introduces several new objects and attributes to your system. Each object is discussed in detail in future chapters.
Policy Package Object. The Policy Package Object is created to hold policies that affect behavior of the agents and programs associated with ZENworks. The ZENworks system looks for these policies when dealing with both users and workstations. A Policy Package Object can be created for each of the supported workstation systems (Windows 3.1, Windows 95/98, Windows NT) and each of the user types (Windows 3.1 User, Windows 95/98 User, Windows NT User), along with miscellaneous collections of policies in a Container Policy.
Workstation Object. This object is created when you import workstations into your tree. This object holds information about the workstation, such as its network addresses and inventory information.
Workstation Group Object. This object is a new group object that enables you to group a set of workstations together. Once the workstations are identified in the group object, you can apply rights and associations to the group just as you do with user groups today.
Cookie Attribute on Container Object. This attribute is used in the process of registering the workstation to the tree. The first time a user logs in to a workstation, the agents register information into the container of the user object. This registration information is placed in this attribute. Additionally, when you import the workstation, this attribute is modified with the DN of the created workstation. The next time someone logs in to the workstation (after your import) the workstation discovers its DN by looking into this attribute, where it originally registered.
Associated Workstations on User Object. This simply keeps track of the workstations that a user registered with NDS by being the first user to log into the tree through that workstation.
The introduction of most of these objects to the tree is of minimal impact. The only object you need to consider is the workstation object. Individually, this object will only introduce approximately 4KB of information. However, the culmination of all workstation objects in your environment needs to be managed carefully, and you must use good design techniques in the placement of your partitions to make your tree most efficient. Included with the ZENworks CD from Novell is a document in the Docs directory called ZENDSGN.HTM that offers some guidelines for tree design.
