AD password changes not reaching ID vault

I have IDM version 4.6.4 running on RHEL 7.  Just recently, the password sync from AD to the ID vault stopped working. If the password is changed in AD, even while connected to the remote loader server, IDM doesn't even register there was an event.  Password sync from the vault to AD works fine. 

Here is the output from the PassSync Troubleshooting Tool. Suggestions welcome.
