I have Samba version 4.3.11-Ubuntu. Ubuntu 14.04 LTS. I have created: - users, who are added to two groups: Code: [email protected]:/home$ cat /etc/group | grep Prace pelnePrace:x:1003:colo064,colo046 odczytPrace:x:1004:colo034,colo075 Group "pelnePrace" need to full access to share "Prace" but group "odczytPrace" need to have only read access. - directory "prace" to share with chmod 770: Code: [email protected]:/home$ ls -l drwxrwx--- 2 administrator administrator 4096 Nov 5 13:42 prace - Samba share (/etc/samba/smb.conf): Code: [Prace] path = /home/prace read only = no writable = yes browseable = yes valid users = @pelnePrace, @odczytPrace #valid users = colo064 read list = @odczytPrace create mask = 0750 directory mask = 0750 write list = @pelnePrace force group = @pelnePrace When I try to login as, for example, user colo064 or colo034 I haven't access to shared directory. What am I doing wrong?
