Remote Servers and Split Boot Servers
121
After the Network Station has booted up, the visiting user selects the
Roam
button on the login dialog. The user then enters the name or address of the
Chicago authentication server (such as
nsm1chicago.mycompany.com or
10.2.1.2 ).
As a result, the Chicago authentication server validate or authenticates the
user ID and password entered, and downloads any user based configuration
information.
Although the IBM Network Station Manager program on the server in Chicago
manages the user-based configuration information, the IBM Network Station
Manager program on the New York server manages the terminal-based user
configuration.
4.5.1 Managing User Configurations at Each Remote Site
There are basically three strategies for building and maintaining user
configurations at remote sites.
4.5.1.1 Fully Centralized Configuration
In this basic model (see Figure 32 on page 122), the Network Stations obtain
everything from the centralized server.
Although it seems that Roam feature and the configuration host IP address
from NVRA are essentially the same, this is not actually the case. The
configuration host IP address is static and the Roam feature is dynamic.
The Roam feature is for mobile users that want to login to a remote system
and access their desktop configuration (user-based settings) wherever they
are. On the other hand, the configuration host IP address option in the
hardware setup utility is used to obtain terminal-based configuration
settings. These two features are not the same and cannot be used
interchangeably.
