SYMPTOMS

If the AS/400 Network Attribute DDMACC is set to a value of *REJECT, the following data providers cannot connect over TCP/IP:

Microsoft OLE DB Provider for AS/400 and VSAMMicrosoft OLE DB Provider for DB2Microsoft ODBC Driver for DB2

If the AS/400 Network Attribute DDMACC is set to a value of *REJECT, testing the connection for the data providers listed above returns the following error messages.

For Microsoft OLE DB Provider for AS/400 and VSAM:
Test connection failed because of an error in initializing provider. User is not authorized to use this command.
For Microsoft OLE DB Provider for DB2:
Test connection failed because of an error in initializing provider. User is not authorized to use this command. SQLSTATE: HY000, SQLCODE: -269

CAUSE

The AS/400 Network Attribute DDMACC specifies how the AS/400 handles incoming Distributed Data Management (DDM) and Distributed Relational Database Architecture (DRDA) requests from remote systems. If DDMACC is set to a value of *REJECT, incoming requests from remote systems for DDM or DRDA access are denied. If DDMACC is set to a value of *OBJAUT, incoming requests for DDM or DRDA access are granted with proper authorization.

RESOLUTION

DDMACC must be set to a value of *OBJAUT for the Microsoft data providers listed above to be able to connect.
