Error description
CICS TG is connecting into a CICS region using an IPCONN which has USERAUTH(VERIFY). This means the USERID and PASSWORD are sent into CICS with each ECI request. When the CTG has to send a PASSWORD it converts it from the clients codepage to codepage 037 and then masks the value. When CICS receives the password it is unmasked and passed to the ESM. If the password contains special characters, they may not be accepted because they have 037 codepoints instead of the codepoints from the CCSID that CICS is using.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All. * **************************************************************** * PROBLEM DESCRIPTION: Incorrect password may get passed to * * the ESM when special characters are * * used. * **************************************************************** In the reported problem a CTG client had a connection into CICS where the IPCONN specified USERAUTH(VERIFY). This resulted in CTG ECI requests arriving in CICS with USERID and PASSWORD credentials. CTG converted the PASSWORD to codepage 037, masked it and sent it into CICS. A codepath exists in DFHISIS where if the LOCALCCSID of the CICS system is not the default (037) and the LOCALCCSID in use has different codepoints for codepage 37 special character(s) then the password may be rejected by the ESM.
Problem conclusion
DFHISIS has been changed to convert the masked password to the LOCALCCSID before passing it to the ESM.
