Use this parameter to require users to specify a user ID and password when connecting to the database server. When selected, QMF for Windows or QMF for WebSphere opens the Set User Information window and requests a valid user ID and password before connecting to this database server. If you do not select this option, you are specifying that the database server you are configuring in the SDF does not require a user ID and password. QMF for Windows or QMF for WebSphere will not automatically open the Set User Information window and request a valid user ID and password.
The default for this option is to require a user ID and password. QMF for Windows Administrator security parameters do not override the database server's security requirements. If the database server requires a user ID and password, QMF for Windows or QMF for WebSphere must pass this information in order to make the connection. By automatically prompting the user with the Set User Information window, QMF for Windows or QMF for WebSphere ensure they have the information.
There are some database servers, ODBC data sources for example, that do not require user IDs and passwords. There are some database servers that accept generic user IDs and passwords. In these cases users might not know a user ID or password. You can clear the User ID and password are required check box to prevent QMF for Windows or QMF for WebSphere from opening the Set User Information window, and allow users to bypass specifying a user ID or password.
Use this parameter to allow users to remotely change their passwords without logging on to the database server. The database server must support this capability and the user ID must have the required authority. This option is only available for DB2 UDB servers that are connected to using TCP/IP, SNA and CLI.
Use this parameter to allow users to save their passwords. Passwords are saved in encrypted format. When checked, QMF for Windows or QMF for WebSphere do not require the user to enter a password in the Set User Information window every time a connection is made to the database server. Instead QMF for Windows or QMF for WebSphere retrieves the saved password. The saved password is used across multiple sessions until a new password is saved or specified. This applies only to connections to DB2 UDB servers.
Use this parameter to specify the type of encryption that should be used when communicating with the database server over the network. This option applies only to DRDA servers. As different types of servers support different encryption options, check with your database server administrator for more information on the type of encryption that the database server you are configuring in the SDF supports. You can select one of the following options:
Use the Enable and Target principal name parameters to allow Windows 2000 clients to use the Kerberos security protocol to communicate with the database server. This option only applies to database servers that are connected to using DRDA. For CLI connections, security options can be set using DB2 Connect(TM) or Client Application Enabler (CAE).
The Target principal name is a string that is used by Kerberos for authentication. If your DRDA communication protocol is configured to do so, you can leave this field blank and the target principal name for Kerberos authentication will be supplied by your DRDA communication protocol.
