User authentication is a natural use of Java and .NET synchronization logic because Java and .NET classes allow you to reach out to other sources of user names and passwords used in your computing environment, such as application servers.

A simple sample is included in the directory %SQLANYSAMP12%\MobiLink\JavaAuthentication. The sample code in %SQLANYSAMP12%\MobiLink\JavaAuthentication\CustEmpScripts.java implements a simple user authentication system. On the first synchronization, a MobiLink user name is added to the login_added table. On subsequent synchronizations, a row is added to the login_audit table. In this sample, there is no test before adding a user ID to the login_added table.

For a .NET sample that explains user authentication, see .NET synchronization example.
