Changes the user password.
A string which is a new password.
The PermissionPolicyUser class declares the protected StoredPassword property to store a password. Passwords are stored encrypted and cannot be changed directly. Use this method to specify a password when creating a new user in code. An example is provided in the Client-Side Security (2-Tier Architecture) topic.
If you need to allow a user to change password using the ChangePassword action, grant the write access to the StoredPassword property.
