Ever figure this out? We're seeing the same problem here. It
was
working for a while for us and then broke at some point. Looks like the
target ou is getting replaced by null at some point.
I installed additional multi-master to our setup with the latest stable
1.3.x version (running Fedora 20). This helped so I suspect it's a bug
with 1.2.25.11 available in EPEL6 stable. At least our data is identical.
