Putting it at the end of the list resulted in smb core dumping :-(

As I explained, this share was a netatalk share and I wanted to retain esp. the tags. This setting did it :-)

You’re right, this was a leftover from my first tests. I was playing with cifs:// mounting (this is SMB1 where the setting makes indeed a difference). But then I realised that we loose all the performance gains with SMB1...

And that’s exactly what I was looking for! Works like a charm :-)
Thanks a lot for the hint!

Changing the umask on the clients can be dangerous, as it is a „global" setting. I only wanted to change it for this share.

Again, thanks a lot :-)
