IMO Sascha says that the group and user entries were written in correct order
to the first provider, successfully passed the constraints there but are then
replicated in different order to the second provider which also checks the
same constraints again. Since the order is significant for the constraint it
fails on the second provider. (Both are configured with same constraints.)

The solution would be to not check constraints for replicated ops. It's
similar to the problem space when/whether to apply slapo-refint,
slapo-memberof etc. in case of replicated ops.
