I turned on replication logging through the GUI, which set it to 8192, 
much as the ldapmodify would have.

What we see on the AD side is that the replication manager says, 
effectively, "Change the password," and then it *appears* that the 
replication manager account attempts to change users to the become to 
the user whose password is being changed; then, the software attempts to 
change the password, which fails. the bad password attempt counter 
increments, and the replication manager account appears to log out.

On the Directory Server side, we see everything connect, the user is 
resolved on both sides, and then after about 15 minutes, the connection 
disconnects due to idleness.

This is the log of the user add using a cleartext password on the ldap side:

That's it, until ten minutes later when I tried to change the password:

Nada.  The badPwdCounter just increments, and the password remains unset.

We were not.  I created a test user with a cleartext password this 
morning, and the result has been functionally identical - the 
badPwdCounter increments, and the user password remains blank on the AD 
side of things.

Oh, hurrah!  Are you also going to change it so that passsync doesn't 
store the password in cleartext in the registry? Our Windows admin just 
about took my head off when he found that. :/  I'll see if I can get him 
to let me use the administrator account on Windows to test with, though.
