An Authorized User license permits a single, specific individual to use a software product. Purchasers must obtain an Authorized User license for each individual user who accesses the product in any manner. An Authorized User license cannot be reassigned unless the purchaser replaces the original assignee on a long-term or permanent basis.
For example, if you purchase one Authorized User license, you can assign that license to one specific individual, who can then use the software product. The Authorized User license does not entitle a second person to use that product at any time, even if the licensed individual is not actively using it.
An Authorized User Fixed Term License (FTL) permits a single, specific individual to use a software product for a specific length of time (the term). Purchasers must obtain an Authorized User FTL for each individual user who accesses the product in any manner. An Authorized User FTL cannot be reassigned unless the purchaser replaces the original assignee on a long-term or permanent basis.
If you notify IBM that you do not want to extend the license term, then you must stop using the product when the license expires.
A Floating license is a license for a single software product that can be shared among multiple team members; however, the total number of concurrent users cannot exceed the number of floating licenses you purchase. For example, if you purchase one floating license for a software product, then any user in your organization may use the product at any given time. Another person who wants to access the product must wait until the current user logs off.
To use floating licenses, you must obtain floating license keys and install them on a Rational® License Server. The server responds to end-user requests for access to the license keys; it will grant access to the number of concurrent users that matches the number of licenses the organization purchased.
