Hello Marc,

by downgrading samba4 from latest 4.2 git to latest stable 4.1 I got rid
of the orphaned entries and it seems that also the RDP issue I had with
Windows 7 machines is gone now.

It seems that currently the samba 4.2 git development tree is not usable.

Thank you for your kind help


best regards

Andreas
