Hey Rowland,

thanks for your feedback.
I did this on a cloned system. Original system is still untouched but I 
have no idea how to work around the initial issue not beeing able to do 
a dbcheck or join since something fundamental seams to be broken for 
this toolchain.

The reason I touched the files in the private dir was that even the 
offline backup failed on this database. I'm afraid I have to recreate 
the domain from scratch unless you have a better idea?

sudo samba-tool dbcheck --cross-ncs -d 5 --fix

Thanks for your patience and help
