The Digas Database Manager must authenticate itself when accessing a database.
In order to do this the DBM checks if there is an appropriate 'database user' within the user properties (in DigaSystem's Admin).
If there are no values entered here, then the DBM next checks under the parameters for that database connection "Digas\Database\ODBCName\" for entries for "User" and "Password" in order to use this login information when necessary.
When these parameters do not exist, then the default user "david" with password "digas" will be accepted as valid database user.
When none of these users are not valid users for the database, an error message will appear (exception is Access, as there is no authentication needed).
