4 <strong>Univention</strong> Directory Manager 80 Users with write access Only the users and groups listed here have write permission for the corresponding share. Inherit ACLs When activating this option, each file created in this share will inherit the ACL (Access Control List) of the directory where the file was created. Inherit owner When activating this option, each newly created file will not be assigned of the user who created the file, but to the owner of the superior directory instead. Inherit permissions When activating this option, for each file or directory created in this share, the UNIX permissions of the superior directory will automatically be adopted. ’Samba custom settings’ tab Custom settings for Samba shares Apart from the properties which can, as a standard feature, be configured in a Samba share, this setting makes it possible to define further arbitrary Samba settings within the share. A list of available options can be obtained by the command man smb.conf. In Key the name of the option is to be entered, and in the Value field the value to be set. Double entries of configuration options are not checked. Attention: The definition of extended Samba settings is only necessary in very special cases. The options should be thoroughly checked before setting since they might have security-relevant effects. Samba extended permissions If a new file is created on a Samba server from a Windows client, the file permissions will be set in several steps: 1. First, only the DOS permissions are translated into UNIX permissions. 2. Then the permissions are filtered via the File mode. UNIX permissions which are marked in File mode, are the only ones preserved. Permissions not set here, will be removed. Thus, the permissions have to be set as UNIX permissions and in File mode in order to be preserved. 3. In the next step, the permissions under Force file mode are added. As a result, the file will have all the permissions set after step 2 or under Force file mode. This means, permissions marked under Force file mode are set in any case.
4.5 <strong>Univention</strong> Directory Manager modules Accordingly, a newly created directory will initially be assigned the same permissions as that which are set as UNIX permissions and in Directory mode at the same time. Then these permissions are completed by those marked under Force directory mode. In a similar way, the security settings are adopted for existing files and directories the permissions of which are edited under Windows: Only those permissions can be changed under Windows, which are marked in Security mode or in Directory security mode. Once this is done, the permissions marked under Force security mode of under Force directory security mode are set in any case. Thus, the parameters File mode and Force file mode, or Directory mode and Force directory mode are applied during the creation of a file or directory, while the parameters Security mode and Force Security Mode or Security directory mode and Force security directory mode are applied when changing permissions. Attention: The security settings only relate to the access via Samba. The user on the Windows side does not receive any notification of the fact that the file or directory authorisations might by changed according to the Samba settings on this tab. File mode The permissions Samba is to adopt when creating a file, provided they are set under Windows. By default, this parameter is set to 0744, i.e. the owner has full access, the group and others have read permission. Directory mode The permissions Samba is to adopt when creating a directory, provided they are set under Windows. By default, this parameter is set to 0755, i.e. the owner has full authorisation, the group and others only have the permission to list the contents of the directory, and to change into the directory. Force file mode The permissions Samba is to set in any case when creating a file, irrespective of whether they are set under Windows or not. By default, this parameter is set to 0000, i.e. no additional permissions are set. Force directory mode The permissions Samba is to set in any case when creating a directory, irrespective of whether they 81
