No MobiLink user authentication   If your data is such that you do not need password protection, you can choose not to use any user authentication in your installation. In this case, the MobiLink user name must still be included in the ml_user table, but the hashed_password column is null.

Built-in MobiLink user authentication   MobiLink uses the user names and passwords stored in the ml_user MobiLink system table to perform authentication.

The built-in mechanism is described in the following sections.

Custom authentication   You can use the MobiLink script authenticate_user to replace the built-in MobiLink user authentication system with one of your own. For example, depending on your consolidated database management system, you may be able to use the database user authentication instead of the MobiLink system.
