Re: Netatalk 2.1.1 Permission

Thanks HAT and Frank

Basically, dperm worked fine on netatalk 2.0.5 but 2.1.1 does not work fine. 

Here is today's last trace. 

I understand dperm depends on parent permission. 


If parent of directory permission is 775, the child will be 775. 
However, It seems modified by another place. 

Here is mkdir results parent parmission was drwxrwxr-x


:DEFAULT: options:upriv,usedots dperm:0775 fperm:0664 maccharset:MAC_JAPANESE ea:sys
~
/local/shared shared 
/local/timemachines TimeMachines


I don't know where is but the result is the following

drwxrwxr-x 4 owner group 4096 Jun  7 23:49 .
drwxr-sr-x 3 owner group 4096 Jun  7 23:49 new folder

We're applying (logical and) the parents mode to the new folder. The
parent happens to be 0755, so...
Is it a bug or a feature?

Cheers, F!
