Question & Answer
Question
Why would I start receiving signon error DFHXS1201 after applying the PTFs in Recommended Service Update RSU1412 to CICS Transaction Server for z/OS (CICS TS) V5.2 or V5.1? The terminal is autoinstalled, then automatically signed on by CA Top Secret using Automated Terminal Signon (ATS). This is the error message I receive:
DFHXS1201 The password supplied in the verification request for userid userid was invalid. This occurred in transaction CSGM when userid userid was signed on at netname netname.
The only difference in a region without the maintenance is that the last message seen is the DFHSN1100 indicating that the terminal was successfully signed on. In the region with the error, there is an extra XS0601 trace entry for INQUIRE PASSWORD that is failing, which causes the sign-on to fail and prevents the automation from running.
Answer
APAR PI21866 added support for the Enhanced Password Algorithm implemented in the RACF APAR OA43999 which applies to z/OS 1.12, 1.13 and 2.1. If these APARs are installed, CICS will call a new callable service IRRSPW00 to for password authentication. This service will be used for basic authentication requests, VERIFY PASSWORD, VERIFY PHRASE and SIGNON requests.
Users of CA Top Secret should apply fixes RO78976 and RO78438 (previously included as temporary fixes TR78633 and TR78438). Contact CA Technologies if you need additional assistance.
