Automatic Directory Information Tree Layout

SIMS provides a mechanism during installation to automatically generate the portion of the directory information tree (DIT) that you plan to implement on a particular mail server. The automatic layout is based on the following assumptions:

		Your organization currently implements the Domain Name Service (DNS).
		The mail server on which you are installing the SIMS software is a valid DNS client.
		If you plan to implement multiple mail servers, you first decide which portions or subtrees of the DIT to implement on each of the mail servers.

During installation, you will be prompted to provide information.

		Mail Server Domain Name - if you plan to implement your organization's entire DIT on this mail server, then you can enter, for example, alpha.com. If you plan to implement a portions or subtrees of your organization's DIT, then you can enter, for example, eng.alpha.com or mkting.bravo.com.
		Organization Top Level Domain Name - regardless whether you plan to implement your organization's entire DIT or a portions of the DIT on this mail server, you must input your organization domain, for example, alpha.com or bravo.com

		Country Name - If you plan to implement one or more mail servers in the same country, then enter the country in which your mail servers reside. If you plan to implement multiple mail servers that are geographically distributed in multiple countries, then enter one country only, for example, the organization's headquarters.
		Organization Name - Enter the name of your organization, for example, Alpha or Bravo.
		Organizational Unit - Enter a name or label for each of the organizational units if your DNS contains subdomains, for example, Marketing or Engineering.

The automatic layout of your DIT is based on the structure of your organization's DNS. In fact, the structure of your DIT will mirror the structure of your DNS.

FIGURE B-6 shows one layer of an organizational unit, whereas FIGURE B-5 does not.

For example, if your organization has fewer than 1000 users (mailboxes), you are implementing one mail server, and you provide the following input:

mail server domain name = alpha.com

organization top level domain name = alpha.com

country = US

organization = Alpha

(when there are no subdomains, there is no prompt for organizational unit name.

If your organization has 100,000 users (mailboxes), you are implementing one subtree per mail server, and you provide the following input for one mail server:

mail server domain = eng.bravo.com

top level of organization = bravo.com

country = US

organization = Bravo

organizational unit = engineering

In the DITs shown in FIGURE B-5 and FIGURE B-6, a final layer with branches called People, Groups, and Services has been added. The People branch will contain user entries, the Groups branch will contain group entries for distribution lists, and the Services branch will contain services. During installation, you can move users and distribution lists from your existing e-mail system to initially populate the directory service. See Section Populating Directory in Chapter "Post-Installation Tasks," for more information on populating the directory.

After the installation is complete, you can use the SIMS Administration Console to maintain (add, delete, modify) the user and group entries, to view the structure of the DIT contained on a particular mail server, and to modify the DIT's organizational units (if subdomains are added or deleted).
