CASSE0021W SIGNON fail. Terminal term-id, TranId trans-id, Program program-id, User user-id, ESMRESP esm-resp, ESMREASON esm-reason.

The program program-id, executing as part of the trans-id transaction, attempted to signon user user-id at terminal term-id, but user-id is either not recognized or an incorrect password was specified.
System Action:
The SIGNON request is rejected.
For Tranid = CESN and Program = dfhzcesn, this should be a duplicate of TXSE0000W and handled identically. Otherwise, the message indicates a user error with the specified program or an error in the specified program's logic.
