This example shows the sequence of events when a user signs on to a PEM
client with an expired password. The sequence is illustrated in
Figure 1 .
- The user attempts to sign on to the PEM client, and supplies a password.
- The PEM client sends the user ID and password to the CICS PEM server.
- The CICS PEM server passes the user ID and password to the external security
manager.
- The external security manager checks the password.
- Because the password has expired, the sign on attempt fails. The external
security manager informs the CICS PEM server, which, in turn, informs the
PEM client.
- The PEM client informs the user that the password has expired, and requests
a new one.
- The user enters a new password.
- The PEM client sends the user ID, the old password, and the new password
to the CICS PEM server.
- The CICS PEM server passes the user ID, the old password, and the new
password to the external security manager.
- The external security manager checks the old and new password.Because
a new passowrd is provided, the sign on attempt is succesful. The external
security manager informs the CICS PEM server, which, in turn, informs the
PEM client.
- The PEM client informs the user that the sign on request has been successful.
