Error: ,1-IDADIDIN16E - USR a7e invalid for CA-IDEAL in CA-Datadictionary I am not sure where the "a7e" is coming from.
Unpredictable problems may happen after upgrading to next release,
if we don't keep track of macro parameter values from previous release.
It may happen to CA Datacom/DB, IPC, Ideal.
Upgrade procedure set the default values at assembly time.
z/os, IDEAL and IPC or DQ any release
In this specific case: Setting SECRTY=Y as it is set in previous release did resolved the case.
If you cannot review the previous macro parameter values then you may compare some settings between two different CICS environments.
See some of them here: ==> DBUT M=SC00OPTS + E7 (SECINF) - Specifies whether SCF enables external security during sign in to determine the signin authorization for the user. N - Does not enable external security checking (default). Y - Enables external security checking. An error message displays if the CA Common Services SSF security interface is not installed during sign in.
==> DBUT M=@IIDOPTS +A2 (default user) (3 chars) (all zeroes means none) - Establishes a default User Definition to use if a match is not found for the signon user ID.
==> DBUT M=@IIDOPTS +A7 (UIDCHK) - Determines whether the signon user ID must match the Advantage CA-Ideal Person Name or User ID.
==> Review Additional information below.

See: README for Ideal https://docops.ca.com/ca-datacom-tools/15-1/en/installing/readme-for-ca-ideal-15-1 extracted: "Sites upgrading, may need to reset various options since the upgrade process will reset options to default values. Use the CA Ideal command PRINT SESSION OPTIONS to save a list of option values before the upgrade. Optionally, create a MEMBER to EXECUTE after the completed upgrade containing the commands to reset site options."
