Mixed case passwords

Problems can occur when RRSF nodes differ in whether they allow mixed case passwords. The MIXEDCASE and NOMIXEDCASE parameters on the PASSWORD option of the SETROPTS command determine whether the system allows mixed case passwords.

Rules: The following rules apply to the case of a password when it is propagated:

When passwords are propagated to a system with NOMIXEDCASE in effect, the result on the target system is a password in upper case.
When passwords are propagated to a system with MIXEDCASE in effect from a system with NOMIXEDCASE in effect, the results differ depending on the type of propagation used:
1. With password synchronization or automatic password direction, if an application (for example, TSO LOGON) sets the new password entered by the user to upper case before passing it to RACF®, the resulting password is in upper case on both systems. If, however, an application sets a lower case password directly via ICHEINTY, the password is in lower case on both systems.
2. With command direction or automatic command direction, the command is sent to the other system as entered. So if the user types a lower case password, the result is an upper case password on the NOMIXEDCASE system, and a lower case password on the MIXEDCASE system.
