[jolie@localhost SambaShare]$ ls -la total 12 drwxrwxr-x 2 Samba Samba 4096 Jun 20 16:20 . drwxr-xr-x 25 root root 4096 Jun 20 16:20 .. [jolie@localhost SambaShare]$ groups jolie jolie : jolie wheel hamachi Samba [jolie@localhost SambaShare]$ mkdir test mkdir: cannot create directory `test': Permission denied [jolie@localhost SambaShare]$ This is confusing to me A directory SambaShare was created with permissions 775 I belong to the group Samba yet I cannot do anything inside the directory? What went wrong?

Hi, Check after change the Owner Group to "Joulie" Check ACLs

I have solved the problem. It turned out that it is a bad feature of Linux, that if you change the group settings when you are logged in, you need to log out and log in again to see the effect.
