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:
- 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.
- 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.
