[389-users] active directory password sync

[Ldap Tester]

I have two 389 servers, one under fedora 12 and one under fedora 11.
They have the following packages:

389-admin-1.1.9-1.fc12.x86_64
389-admin-console-1.1.4-2.fc12.noarch
389-admin-console-doc-1.1.4-2.fc12.noarch
389-adminutil-1.1.8-4.fc12.x86_64
389-console-1.1.3-5.fc12.noarch
389-ds-1.1.3-5.fc12.noarch
389-ds-base-1.2.5-1.fc12.x86_64
389-ds-base-devel-1.2.5-1.fc12.x86_64
389-ds-console-1.2.0-5.fc12.noarch
389-ds-console-doc-1.2.0-5.fc12.noarch
389-dsgw-1.1.4-1.fc12.x86_64

389-admin-1.1.8-4.fc11.x86_64
389-admin-console-1.1.4-1.fc11.noarch
389-admin-console-doc-1.1.4-1.fc11.noarch
389-adminutil-1.1.8-3.fc11.x86_64
389-console-1.1.3-4.fc11.noarch
389-ds-1.1.3-4.fc11.noarch
389-ds-base-1.2.5-1.fc11.x86_64
389-ds-base-devel-1.2.5-1.fc11.x86_64
389-ds-console-1.2.0-4.fc11.noarch
389-ds-console-doc-1.2.0-4.fc11.noarch
389-dsgw-1.1.4-1.fc11.x86_64

There are set up as multi masters.

I also have a windows 2003 Active Directory server.
I have password sync'ing set up between the AD and the fedora 12 389 server.

This has been working for several years.
I have recently noticed a problem that may have existed for some time now,
maybe always.

If I change a user password via windows, everything works as expected.
The password changes on windows and both fedora machines.
If I change a user password via the fedora 12 machine,
the one that has the sync agreement with the windows machine,
again, everything works as expected,
The password changes on windows and both fedora machines.

However, if I change a user password via the fedora 11 machine,
the one that does not have the sync agreement with the windows machine,
then, the password changes on both fedora machines,
but NOT on the windows machine.

This is not how it is supposed to work, right?

I have looked at all sorts of logs, and still have now clue as to the
problem.
(I do not believe it is a fedora 11 versus fedora 12 problem.)
Does anybody have any ideas?
