Most of it's been said but remember that if you are intending an autoland on a Cat I ILS (or even Cat 2/3 when LVP are NOT in force) that objects such as aircraft and vehicles etc may well be manoeuvring and affecting the integrity of the ILS which may cause an autopilot disconnect at an embarassing time!
I recall doing a practice autoland years ago on the B737-300 on a Cat 3 ILS when LVPs were NOT in force when the autopilot disconnected after the nose up trim had been applied by the automatics at 400 ft and having to do some pretty rapid retrimming and correction of the approach to ensure a safe landing. The oscillation on the localiser had been caused by an aircraft that had departed and overflown the localiser transmitter when we were on short final.
In summmary, by all means autoland off a non-protected ILS but exercise caution!
