Licenses limit how many components you can install on a network, and how many users can connect to your servers.
If you notice messages similar to these errors in the Unwired Server log, then connection requests from registered users have exceeded the licensed limit:
2009-12-28 18:01:59.872 INFO MMS Thread-19 [com.sybase.sup.server.lm.LicenseUtil] The number of registered devices has reached the maximum limit for your license. 2009-12-28 18:01:59.965 INFO MMS Thread-19 [com.sybase.djc.mobilink.LoginHandler] The number of registered users has reached the maximum limit for your license. 2009-12-28 18:02:00.168 ERROR Mobilink Thread-19 [com.sybase.ml.sup.Logger] [-10052] authenticate_parameters scripts return 4000
For example, a trial license limits you to only five device users. If a sixth user tries to connect, the error is logged accordingly.
