I set 'profilePath' to '//raspberrypi/profiles' in my AD object, unfortunately the 'raspberrypi' that is running now isn't the same one that was running when I set it and it doesn't have a profiles share. The question has to be, is this a Samba problem, or is it a Windows problem ? To me, it seems that Windows looks for the profile and having not found it, searches on 'raspberrypi' for it, so should Windows be doing this and should Samba be allowing this ? Rowland

I'm merely reading the log you posted. There's obviously something strange here. If I send you some extra-verbose debug patches for that area of the code can you run with it so I can check something. I'm starting to have a suspision about the directory scanning code...
