I have an executive wanting to change his password to something only he knows. I recently worked on his Macbook Air and needed his password so he gave it to me. So now he wants to change it on his own and I dont know how to go about that in OS X. I know this is possible in windows by just hitting CTRL+ALT+DEL and clicking Change Password. Is there anything similar to that in OS X? I am running Lion on a new Macbook Air and it is bound to our AD. Thanks in advance.
