    Adding user authentication to your application

Enabling user authentication

Enabling user authentication requires the application to supply a valid UltraLite user ID and password when connecting to the UltraLite database. If you do not explicitly enable user authentication, UltraLite does not authenticate users.

To enable user authentication (C++ API)

1. Define the compiler directive UL_ENABLE_USER_AUTH when compiling ulapi.cpp.

2. Call ULEnableUserAuthentication before opening the database. For example:

   ULData db;
   ...
   ULEnableUserAuthentication( &sqlca );
   db.open();
   ...

Once you have enabled user authentication, you must add user management code to your application. For more information, see Managing user IDs and passwords.
