I have a pretty much default Active Directory driver install setup. I
have users in both eDir and AD that are not associated. A user in eDir
changes their password. This gets turned into a Synthetic Add since the
user is not associated. The Match rules happen and a match is found
(matches on Full Name). At this point, I still see
nspmDistributionPassword in the document. Now the MERGE happens. After
this point, the nspmDistributionPassword is gone, so the user's password
never gets synchronized.

Why am I losing the nspmDistributionPassword after the merge? Is there
any way around this?
