SMB create mask has no effect

Hi,

I set this two advanced options in my SMB configuration

create mask = 0600
directory mask = 0700

but when i look in the share new create files and directories have the default user acc-rights:

root@OMV:/media/ce861792-b1fb-42a3-a229-22bd9bc2e811/MServ# ls -l
drwxr-xr-x 2 MServ users 4096 Jul 26 18:34 test dir
-rwxr--r-- 1 MServ users 3625 Jul 24 18:55 test file.txt

For any reason this extra options are totally ignared. Anyone has an idea how to fix this?

Greetings

Monchi
