[Samba] samba -v- unix file/group permissions
In migrating to Samba on FreeBSD from WinNT, I've run into this hitch. Let us say I have 9 users named User1, User2, User3, ? User9 User1 is a member of group wheel User2 & User3 have the administrative task (add/change/delete) of managing the content of the directory Dirc1 and all subordinate objects (files and directories). Dirc1 is the directory /usr/Shared/Dirc1. Only User1 will need to delete Dirc1, but if it helps then User2 & User3 can also delete Dirc1. All users can read anything in Dirc1 and all subordinate objects as well. All users can contribute (add/change/delete) anything in the Everyone directory which is /usr/Shared/Dirc1/Everyone Shared is a Samba service. As User2 & User3 add new objects subordinate to Dirc1 they are to retain the permissions necessary to add/change/delete all current and new objects in Dirc1. All users can add/change/delete anything anywhere else in Shared All end-user efforts are performed from Windows NT workstations. (This is essentially what I have on an NT file system and would like to maintain this structure to prevent confusion.) Finally, Samba ACL support is not compiled into Samba because that option is broken between this version of FreeBSD and this version of Samba. 1) How do I configure the Shared, Dirc1 & Everyone directories in terms of the Unix file permissions and ownerships to support this? 2) How do I configure the Shared service in Samba to support this? 3) How do I configure the User2 & User3? 4) What else will be necessary? In Linux, can groups be members of other groups? In BSD groups cannot. I think I'm going to learn to hate this about Unix. On the issue of Force group / force user. These properties take presence over the actual user: group properties of a users connection such that if force user and/or force group is implemented on a share then all users of that share are controlled by the force user/force group assignments. So this did not work. I expect force create mode to be similarly effective for all objects on the share which will not work for me. I thought to have: root : wheel drwxrwxr - x for /usr/Shared root : Dirc1-admins drwxrwxr - x for /usr/Shared/Dirc1 and root : Dirc1-admin drwxrwxrwx for /usr/home/shared/Dirc1/Everyone Dirc1-admins= User2, User3 Where Shared is defined in Samba as: [shared] path = /usr/Shared browsable = yes read only = no writable = yes available = yes My problem here is when creating new objects I have to manually fix the group permissions. Can this fix be automated and the time the file is created regardless of who created the object? Thanks, -Steve Lyle 513.557.5207
