Like Gmail, when an user changed his Windows Password, have a notification to explain there is a synchonization problem.
Invite the user to change his password instead of go to his mails accounts.
for iOS specifically, our users often forget to change the iOS mail password after changing their AD account, resulting in the account being locked (iOS try and try again, until locking the account).
It would be nice for SMC to display a notification on the phone when the AD password is changed., to remind the user to do the same on the phone (competitors are doing it, perhaps based on the password last set value in AD)

Very interesting idea. People can be inform to change his password by a notification send by SMC.
