Here's an excellent new lab guide that will help you quickly establish a test lab deployment of Novell eDirectory on the Linux operating system. Specifically, it will walk you through the setup of Novell eDirectory 8.7.1 on SUSE Linux Enterprise Server 8.2. While the processes described in this document can be followed using different Linux distributions and Novell software versions, for best results, we recommend using the same software and versions noted in this guide.

To obtain copies of Novell eDirectory 8.7.1 and Novell iManager, go to http://download.novell.com. The SUSE Linux distribution can be downloaded from Novell or purchased through most major software retailers. You'll also need an LDIF file, which you will use to import sample directory objects, and a schema file, which you will use to extend the eDirectory schema. Both files can be downloaded from http://www.novell.com/coolsolutions/tools/1791.html.

10 Million Pentium III 450-700 MHz (2-4) 2 GB+ 15 GB

eDirectory Installation

Make sure that you have the eDirectory license file available on either a floppy disk or on the hard drive itself. The easiest thing to do is to place the license file in the installation directory located at Linux/setup/.

Depending on which method you are using to install eDirectory, the way you invoke the installation script will be slightly different.

If you are using the installation CD, you need to mount the CD. This can be done simply by entering mount /media/dvd or mount /media/cdrom at a system prompt, depending on whether you have a DVD or CDROM drive.

  1. Open a terminal window by right-clicking the screen and selecting the "New Terminal" option from the drop-down menu.


  2. Enter su at the command prompt to change to the root user, then enter the password for the root user. Notice that the prompt will change so that the # sign is shown. This indicates that you are the root user.


  3. Go to the directory of the setup script by entering cd media/cdrom/Linux/setup/ or cd media/dvd/Linux/setup/ at the command prompt.


  4. Enter ./nds-install at the command prompt to run the install script.


If you downloaded the tarball, you need to unzip and untar the file before you run the install script.

  1. Open a terminal window by right-clicking the screen and selecting the "New Terminal" option from the drop-down menu.


  2. Enter su at the command prompt to change to the root user, then enter the password for the root user. Notice that the prompt will change so that the # sign is shown. This indicates that you are the root user.


  3. Use tar zxvf <filename> to untar the program.




  4. Go to the setup script directory, then enter ./nds-install to run the install script.


  5. After the introduction screen finishes scrolling down the screen, press Enter to continue.


  6. You are prompted to read the License Agreement. You can use the spacebar to scroll through it a page at a time. Once you reach the end of the agreement, you can choose to accept it (y), not accept it (n), or quite the installation (q).




  7. Enter 1,2, then press Enter to select the eDirectory Server installation.


  8. If you have already placed the license file in the setup directory, the install script will continue unimpeded. Otherwise, the install will prompt you for the location of the file.


  9. The setup will automatically install the necessary RPMs, then exit. Read the readme.txt file located in the Linux/ directory (located one directory above where you are currently) before continuing with the eDirectory tree configuration.


  10. Use ndsconfig to set up your initial tree. Enter ndsconfig new -t DA_TREE -o 8000 -O 8443 at the command prompt.




  11. When you are asked for the admin name, enter admin.DA. Enter novell for the password. For the server context, enter da.


eDirectory is now set up on the server.

Part V: Setting Up a DCHP Server

In this section, you will learn how to set up DHCP on your server.

  1. Open the openoffice.org word processor application. On your Ximian Desktop toolbar (at the top of the screen), there should be an icon that has a pen on it. Click that icon to open the word processor.


  2. Once the application is open, click File, then click Open. In the filename box enter /usr/share/doc/packages/dhcp-server/examples/simple_dhcp.conf.


  3. Click File, then click Save As. In the filename box enter, /home/<name_of_your_user>/dhcp.conf (for <name_of_your_user> enter your username).


  4. Edit the following lines




  5. to be as follows:



    Save the file, and then exit the program.

  6. At a command prompt as root, enter mv dhcp.conf.txt /etc/dhcpd.conf.

  4. Enter yes for the express install.


  5. Scroll through the license agreement using the spacebar to read a page at a time, then enter y to accept the agreement.


  6. Enter the admin name, context, and password. You will be prompted for a PCO password (the syntax is "cn=admin.o=da"; use novell as the password). Because this is a fresh install, use the same password that you used for the admin password.


  7. When you are prompted to make any changes, enter no, then press Enter.


  8. Scroll through the documentation screen, after which you will be finished with the iManager install.

Part VII: Extending the Schema and Importing an LDIF File

Now you will prepare and populate your directory.
