Mixed case password support not working when UCTRAN is YES if using ACF2

Troubleshooting


Problem

You are testing strong password specifically for mixed case passwords. You are unable to logon to CICS when you specify UCTRAN(YES). The CICS documentation says the UCTRAN option is temporarily set to NO if support for mixed case passwords is active. With UCTRAN set to NO, the mixed case password is accepted. You are using CA ACF2 for your external security manager .

Symptom

Section CESN - sign on in the CICS Transaction Server documentation states:

For mixed case passwords to be supported, ensure the PROFILE for the signon transaction CESN/CESL is specified UCTRAN(NO). Otherwise, user IDs and passwords that are specified in the CESN transaction are converted to uppercase. However, if support for mixed case passwords is active in the external security manager, CICS saves the value of the UCTRAN option and temporarily sets it to UCTRAN(NO) while the user is prompted to enter a userid and password. CESN then uppercases the userid but leaves the password in the case entered by the user. When the CESN transaction completes, the UCTRAN attribute is restored to its original value. If the user disconnects from the terminal before the CESN transaction is completed, the terminal might be left with the UCTRAN(NO) attribute set.
