iManager provides an easy method for changing Middle Tier Server (also known as XTier) configuration after Novell® NetStorage or Novell ZENworks® Desktop Management 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 registry changes made to one node in the cluster must be made to the registry of each node in the cluster. After you change one node, run iManager on each node in the cluster and make the same changes. To implement the changes, restart the NetStorage service on that server.
If the NetStorage service is running on a NetWare server, you need to stop and restart the Apache Web server.
To stop the web server, run the following command at the terminal console.
Ap2WebDn
To restart the Web server, run the following command at the terminal console.
Ap2WebUp
If the NetStorage service is running on a Linux server, run the following command at the terminal console to restart the NetStorage service.
rcnovell-xsrvd restart
This lets you view or edit the following configuration settings.
Proxy Username and Proxy Password
The admin username and password that you entered when you installed
your NetWare server or when you installed Novell Open Enterprise Server (OES) on your Linux server. If you want the Middle Tier Server to use a different username
and password for administrator access, type them in the fields provided.
If you click the Set Defaults button, the value will be set to whatever value appears in the Default Value column. If there is no value in the Default Value column, the value will be set to blank (no value).
Note: If Netstorage is configured to use OES common proxy, then the proxy user password must not be changed from this interface.
Location
The registered location you want users to specify as part of the Middle
Tier Server URL to access the Middle Tier Server. The default is oneNet.
If you change this registry setting, you must also edit the etc/opt/novell/xtier/xsrv.conf file and change the /oneNet setting in the Location section (first section) to the same setting you specified in iManager.
Session Timeout
The amount of time (in seconds) that the session will remain idle before it
is terminated. If there is no Middle Tier Server activity for this amount
of time, the user will be required to log in again to the Middle Tier Server
before being allowed file access.
Janitor Interval
This setting should not be changed except under direction from Novell.
Persistent Cookies
The Persistent Cookies option can be turned either on or off. With the value
set to 0, Persistent Cookies is turned off. Persistent Cookies is turned off
(the default) if there is no value or the value is set to 0.
With Persistent Cookies turned off, the NetStorage will end when the user closes the current browser or Web folder. Also, if the user has a current instance of NetStorage running in a browser window or Web folder and he starts up a new browser instance or Web folder, he will be required to reauthenticate.
Turning off Persistent Cookies can be beneficial if you have workstations that are shared because as long as the browser instance is closed down, the next user of the workstation cannot accidentally or intentionally obtain access to your network through NetStorage.
Leaving Persistent Cookies turned on can be beneficial if your workstations are not shared because it prevents users from having to unnecessarily reauthenticate.
If the user selects the Logout option in NetStorage, the session will end regardless of whether Persistent Cookies is turned on or off.
LDAP Port
Lets you change the LDAP port number if there is a conflict between Active Directory and eDirectory for LDAP requests.
This conflict exists because the backend is acting as a domain controller, which has Active Directory installed on it. The conflict is created by both eDirectory and Active Directory attempting to use the same default port (the default port number is 389). Active Directory normally wins the conflict. The Proxy User object type exists in eDirectory but not in Active Directory. Because of this, when the Middle Tier Server tries to bind as a Proxy User, the bind attempt fails. This is also the reason LDAP lookups fail.
Cookieless
The Cookieless option can be turned either on or off. With the value set to 0, Cookieless authentication is turned off (the default). Cookieless authentication can be turned on by setting the value to 1.
Cookieless authentication is needed for some clients that use versions of WebDav that don't support cookies. For example, Apple clients use a WebDav version that does not support cookies.
If Cookieless Authentication is turned on, you must close all browser instances to logout.
ClosestEDirServerDN
If used, this option requires the distinguished name of the closest eDirectory
server where needed applications distributed by ZENworks Desktop Management
might reside. The default value is MyServer.MyOrg.
This field works in conjunction with "Site Lists" defined for Application objects in ZENworks Desktop Management. When the user has logged on through a Middle Tier Server at his or her site and clicks on an Application icon, the Middle Tier Server determines the location of the nearest eDirectory server where a needed application (defined in the site list) has been stored. The application file is then distributed to the workstation and installed. For more information about Site Lists, see Setting Up Site Lists in the ZENworks 7 Desktop Management Administration Guide.
The Site List feature is valuable when users move from one site to another and need access to applications on his or her home server, but distribution of those applications over a WAN may be time or cost prohibitive. When a closer eDirectory server contains the application(s) a user needs and site lists are set up, more efficient application distribution is realized.
