It works, itīs the security translation wizard that has to be run on the workstations and or servers to translate the old SIDs in the ACLs to the new ones. That comes a little bit like a double treat with the SID-history, that allows users to access data with old SIDs, but annyway, itīs functional. And I donot have to write a script :).

Thanks a lot to everyone for his (her) help.
