[cifs-protocol] highest_usn and tmp_highest_usn in highwatermark < max usn sent in getcchanges

Hello Dochelp,

In my quite old provision it turned out that the instanceType for the 
root DN of the schema partition (CN=Schema,CN=Configuration,DC= ...) had 
a wrong value (old provision, bad knowledge of all AD stuff, so we made 
what we thought was good).

In a getncChanges reply from a Windows 2003R2 server the highest_usn and 
tmp_highest_usn are lesser than the USN of one change.

As a result samba keeps on asking this change, here is the dump of the 
getncchange reply.

Can you explain why the highwatermark's USNs are lower than the highest 
usn in the changes transmitted ?
