first time writing but I'm desperate and I think you can help me ... my English is very bad I speak Spanish ... I install Samba4 on Ubuntu 12 and all is well, I can join computers to the domain and can create users. My problem is the permissions, not how they work! I need the owner capeta have all permissions and other users can see the contents of the folder and read but not modify or delete ... I can not get that .. try all combinations of permissions on linux and does not work .. also try changing the permissions on the Security tab in the administrator users and groups windows and does not work .. how can I get the owner has full control and others only see the content without removing or changing? Thanks for taking the time to help me ...
What Samba version your are using? Can you show the content of your samba4 configuration file (smb.conf)? To enable windows permission in samba4 you need install acl package and modify your /etc/fstab; you can follow the instructions in the wiki: https://wiki.samba.org/index.php/Samba_4/OS_Requirements
My recommendation is build samba4 by yourself (clone de git repository or download the latest tarball from the official samba site). Also you can use the SerNet repository or if you plan to use Debian, you can use the debian backports repository.
I very important if you can show the result of the samba-tool testparm command.
Check the above and tell me.
