iManager provides an easy method for changing Middle Tier Server (also known as XTier) configuration after Novell® NetStorage or Novell ZENworks® for Desktops (ZfD) has been installed. Middle Tier Server configuration information is stored in the NetWare® registry on NetWare servers. On Linux servers, Middle Tier configuration is stored in an XML file on the Linux server.

Important: If you are running in a clustered environment, any Middle Tier configuration changes made to one node in the cluster also must be made to the other Middle Tier servers in the cluster.

Changes go into effect when you restart the server or when you restart Apache Web server.

To restart Apache Web server on a NetWare server, at the server console, enter

Ap2WebDn

to stop the Web server and then enter

Ap2WebUp

to restart the Web server.

To restart Apache Web server on a Linux server, at the command prompt, change to the /etc/init.d/ directory and enter

./apache2 restart

Authentication Domain

This page lets you change or add the eDirectoryTM server URLs and contexts that are required by the Middle Tier Server. This page also lets you add support for dotted usernames, e-mail address usernames, and Universal passwords, as well as giving you the option to change the eDirectory server that is designated as the Primary. See the NetStorage documentation for more information about eDirectory server URLs and contexts.

The following are Authentication Domains check box and button descriptions.

Universal Password
Enabling this option allows Universal passwords to be used for NetStorage authentication.

Universal password functionality is disabled by default. If you have enabled Universal passwords, enable this option to let users with Universal passwords authenticate through NetStorage.

Add Domain
Adds another eDirectory server IP addresses or DNS name. Users are authenticated to this eDirectory server.

For example:

Middletier.boston.digitalair.com

or

111.22.33.4

Make Primary
Makes the eDirectory server URL listed above the button the Primary.

Remove Domain
Removes the eDirectory server URL from the list of URLs used by the Middle Tier Server.

Remove Context
Removes the context (if there is one) from the eDirectory server URL.

Add Context
Adds an eDirectory context to the eDirectory server URL. This context must be formatted using the eDirectory distinguished name. Make sure that you separate the context by periods and not commas (for example: users.digitalair).

Add Host
Creates a list of alternative hosts for the Authentication Domain.

If the Middle Tier Server cannot reach the host specified in the domain, it searches the Other Hosts list specified in the Value field to find another server to use for authentication. Type DNS names or IP addresses of alternate servers separated by a comma delimiter in the Value field.

For example, you could enter a string similar to the following:

Middletier.boston.digitalair.com,Middletier1.boston.digitalair.com

or

111.22.33.4,111.22.33.40

Context Priority
Lets you specify a priority for the context assigned to the eDirectory server URL. Adding a context priority lets you specify the order you want the different contexts searched.

If no context priority is specified, the default priority is used, which is 0. The priority range is from 0 (lowest) to 9999999.
