Andrew,

>I'm having a hard time understanding the following statement in the MMDevGuide :

>Note: If you are using SQL Server authentication, you only need to specify a user id (sa) and password (if any) on your development machine so the MM .NET builders can access your database. On end-user's machines at runtime, the user id and password are determined dynamically based on the user login information.

>Does this mean that the login information given in the mmUsersFormLang will be used to connect to the database (I get a user(null) exception if I remove uid and pwd from the connection string). Also, does this mean that the user must be listed in the database's user list as well as the mm Users table?

That's right...the information entered in the Login form will be used to connect to the database. This would also require you to enter the user information in SQL Server and the MM User's table. For more information on initially connecting to the database, see the MM .NET Dev Guide topic "Step 5: Displaying a Login Form". Alternately, you can use Windows Authentication to connect to SQL Server and completely bypass the need for id and password. Another good MM. NET Help topic that relates to this is "Integrating with Windows Security".
