The following concepts and terms describe how NLS supports the User Access License (UAL) model.
Search for a license unit---A function that the License Service Provider (LSP) performs when an NLS client requests a license unit
When an NLS client requests a license unit in the User Access Licensing model, the license service provider first searches the User object's context for an available license unit. If the license service provider doesn't find a license unit, it searches up the eDirectoryTM tree for one.
Licensed User object--- A User object that has successfully logged in to the network and obtained a license
Unlicensed User object---A User object that does not have a license unit Scenario: You install licenses for 100 users. The company hires 10 more employees, and you create network accounts for them. Even though 110 user accounts exist, only the first 100 users that log in, can gain access to the network until 10 more licenses are added to accommodate the 10 unlicensed users.
Hard stop---A feature that prevents a user from accessing an application or service when there are no more licenses available Scenario: You install licenses for 25 users. All 25 license units are in use when the 26th user attempts to log in. Because no license units are available, the user will not be granted network access. Solution: To allow the 26th user to log in to the network, you must install additional licenses or release a license that is currently in use. Releasing a license that is in use revokes network access for the User object that had the license, the next time the user attempts to log in.
