Release 10.1A: OpenEdge Getting Started:
Core Business Services

Disallowing the blank user ID

You can prevent the blank or default user ID from connecting to an OpenEdge database when connecting with a Release 10.1 or later client.

You select the option to prevent blank user IDs from accessing the database by choosing Admin Database Options Disallow BlankUserId in the Data Administration tool. For details, see the Data Administration Help.

Note: Choosing the Disallow Blank UserId option from the Admin Database Options menu is different from choosing Disallow Blank Userid Access from the Admin Security menu. In the latter case, you are allowing the user to access fields and tables in the database as long as the field- and table-level permissions allow it and the procedures being run are precompiled.
