For sure it might be a attack vector, I'm with you here.

The reason for setting the share permissions here is the recommendation 
in the wiki, sorry I forgot to include a second link in my initial post:
https://wiki.samba.org/index.php/Windows_User_Home_Folders#Setting_up_the_Share_on_the_Samba_File_Server

I'm following this wiki howto to setup the "Users" Share. This share 
should be used for folder redirection later to hold users personal data. 
As I'm no windows expert I am unsure if I _really_ need those share 
permissions or not.
Anyway, using the Security Tab is working as expected.

Just for information: I have a very old self-compiled samba 4.6.4 
running on a different server. Just to be sure I tested the permissions 
tab settings on a share hosted on this server and it works flawlessly. 
share_info.tdb also has 700 permissions like my brand new debian.

Cheers
Thomas
