It would appear the older build had the syncprov module built in
statically, while the newer build has it built in dynamically, so at
this point you would need to moduleload syncprov.
Yes, thank you, reverting to the module built in solved it for now.
Next will be to reconfigure to load dynamically, but not on a
production system, need to learn and check before...
