How to Fix Authorized Computer Can’t Sync Apps from iTunes to iPhone

Someone complain the sync problem on Apple community like this:

(He has authorized his computer but he got the message)

This computer is already authorized.  You have used 1 of 5 devices.  BUT when I click to sync that same iPhone one second later...I get this message:

This computer is not authorized for apps that are installed on the iPhone.  Would you like to authorize this computer?  If you do not click authorize, 7 apps will be deleted from the iPhone.  Would you like to authorize? I click 'authorize' and put in my user id/password and I get back the message that this computer is already authorized and I have used 1 or 5 devices.

AND then it brings up the message AGAIN that this computer is not authorized for the apps and the vicious cycle never ends. In the process, all of the apps on the iPhone were purchased using the same ID as he is using on his computer.
