In order to change the expiration date for an Active Directory user password, you need to first make sure the following measures are taken:

1. Check whether the user has set a password complexity policy: This ensures that the user’s password is secure by meeting a certain set of standards.


2. Check the password expiration policy: Every password has an expiration date associated with it. This should be confirmed in order to avoid any undesired changes.


3. Check the user’s account access settings: It is important to confirm that the user’s access settings are set and are in accordance with the administrator-defined policies.


4. Restrict the user’s account access rights: This ensures that the user can only access resources that are allowed.


5. Check the user’s password policy: Ensure that the password policy is setup to meet industry standards and provides the right level of protection to users.


6. Enforce periodic password changes: Set a frequency for periodic password changes to ensure that user passwords remain current and updated.


7. Set up user authentication measures: Ensure that user authentication measures are in place to protect the security of user accounts.
