The Client daemon also
maintains a user ID and password for each installed terminal. These
values override any default values set for the server connection.
Terminal security is usually required only if using sign-on incapable
terminals.
Password expiry management
For CICS® clients,
the management of expired passwords can be handled by the ESI functions CICS_ChangePassword and CICS_VerifyPassword.
On Windows,
you are prompted specifically for any unknown user ID, incorrect password,
or expired password, after you enter your user ID and password in
the security dialog.
Sign-on capable and sign-on incapable terminals
Sign-on capable terminals allow sign-on transactions, either CICS-supplied
(CESN) or user-written, to be run, whereas sign-on incapable terminals
do not allow these transactions to be run.
