Password case sensitivity using a local operating system registry

Knowing when a password is interpreted as case sensitive or not can directly affect how you use a local operating system registry. WebSphere® Application Server exploits the mixed case password option for the Resource Access Control Facility (RACF®) and allows you to use case sensitive passwords.

z/OS Version 1.7 RACF

In z/OS Version 1.7, RACF supports the option of a mixed case password. You select this option for RACF by using the SETROPTS PASSWORD(MIXEDCASE) command. To use case sensitive passwords in WebSphere Application Server for a local operating system registry, you must comply with all of the following requirements:
  1. Use z/OS Version 1.7 or higher
  2. Use the local operating system registry
  3. Turn on the RACF mixed case option with the SETROPTS PASSWORD(MIXEDCASE) command
Important: All three of these requirements must be met; otherwise, WebSphere Application Server password will not be sensitive to case.

If you use a Lightweight Directory Access Protocol (LDAP) configuration, you can use mixed case passwords.

For more information on the mixed case password feature in z/OS Version 1.7, see Z/OS V1R7.0 Security Server RACF Security Administrator's Guide. This guide is available under "Security Server and Integrated Security Services. Within the guide, see section 5.2.1.
