h2. JetBrains License Server
JetBrains License Server is a web application that enables license administration across a single network. The License Server serves as a central point for distribution of licenses among multiple users and client machines in a network environment, and it supports the following JetBrains products:
• IntelliJ IDEA 7.0 and higher
• ReSharper 3.1 and higher
License Server issues and revokes license tickets to/from network clients based on properties of license keys that are provided by JetBrains after purchase. The following two types of license keys are supported by the License Server:
• Single-user license key that allows a customer to access a product by a _specific number of concurrent users corresponding with the number of purchased license keys_ run by the License Server;
• Multi-user license key that allows a customer to access a product by _unlimited number of concurrent users_ pursuant to a separate license agreement with JetBrains that implies regular monitoring of the concurrent product usage and providing usage reports to JetBrains on the quarterly basis for the purpose of the license "true-up".
If you have obtained a number of single-user license keys, you can download the License Server below and start using it without any additional access permission. If you are interested in a multi-user license key, please [contact sales|http://www.jetbrains.com/eshop/assistance/displayAssistance.do] for information on the licensing terms.
