What’s New
The following are new features added to the Novell®ClientTM for Linux 1.2:
• The ability to edit login scripts from an option on the tray application menu.
User authentication and access control are enforced (that is, users must be logged in to edit
their personal login scripts). eDirectoryTM access control is enforced as well, which is useful
when administrators do not want their users to be able to edit their personal login scripts. An
administrator can also configure the Novell Client for Linux to disallow the Edit Login Script
option so it is not displayed on the on the tray application menu.
For more information, see “Editing Your Login Script” in the Novell Client for Linux User
Guide.
• An integrated login feature that allows login profiles to be stored for use by subsequent
network login operations.
This functionality makes use of CASA (Common Authentication Services Adapter) for
persistent storage of credentials for a given realm. The overall concept is that if the Novell
Client for Linux 1.2 or later and CASA 1.6 or later are installed on the workstation, users can
have their eDirectory connections, login scripts, and startup drive mappings run when they
initially log in to the workstation. This authentication does not replace the workstation login; it
currently just augments it with eDirectory functionality.
Users must run the normal Novell Login from the tray application menu and save their
Novell Login settings. After saving the Novell Login settings, the next time the same user logs
in to the workstation, eDirectory authentication is automatic and the user’s login script runs at
startup.
For more information, see Section 4.1, “Setting Up Integrated Login,” on page 25.
