About Password Expiration
Password expiration can be implemented in the following authentication strategies:
Security adapter authentication: LDAP or applicable custom security adapter
Database authentication where supported by the RDBMS
If you are using an LDAP security adapter, then password expiration is handled by the external LDAP directory, and is subject to the configuration of this behavior for the third-party directory product.
For example, when a password is about to expire, the directory might provide warning messages to the Siebel application to display when the user logs in. Such a warning would indicate the user’s password is about to expire and must be changed. If the user ignores such warnings and allows the password to expire, then the user might be required to change the password before logging into the application. Or, the user might be locked out of the application once the password has expired.
Password expiration configuration steps for each directory vendor will vary. For more information, see the documentation provided with your directory product.
