Implementing Siebel Business Applications on DB2 UDB for z/OS > Security Concepts for z/OS >

Operating System Security

The DB2 Connect middleware passes the user name and password used to access Siebel Business Applications to DB2 to establish a connection. The user name and password can be user credentials supplied by the external security adapter, if you are using an external security adapter.

The Security Administrator (or someone who has been delegated this authority) must preregister all user names and passwords passed through DB2 Connect with the z/OS security package in use, for example, RACF, ACF/2, or TOP SECRET. The z/OS Security Administrator can associate the user name with a secondary authorization ID (also known as the Security Group ID on the Deployment Planning Worksheet) within the z/OS security package to simplify database security privilege administration.

DB2 Connect supports password encryption on the DB2 for z/OS platform.

NOTE:  Siebel user IDs and passwords for DB2 are case-insensitive.
