UltraLite C++ User's Guide
  Understanding UltraLite Development

User authentication

There is a common sequence of events to managing user IDs and passwords.

  1. New users have to be added from an existing connection. As all UltraLite databases are created with a default user ID and password of DBA and SQL, respectively, you must first connect as this initial user and implement user management only upon successful connection.

  2. You cannot change a user ID: you add a user and delete an existing user. A maximum of four user IDs are permitted for each UltraLite database.

  3. To change the password for an existing user ID, use the Connection.GrantConnectTo method.
