Hello All I am trying to use nfs4acl_xattr plugin from samba source code. https://www.samba.org/samba/docs/current/man-html/vfs_nfs4acl_xattr.8.html I mounted NFSv4 mount point locally and exported it through samba with vfs objects set to nfs4acl_xattr. *[root at test3 ajain]# net conf showshare local[local] path = /home/ajain/mount comment = local share guest ok =

Hi All I found there is one bug in the plugin. The name of the attribute for ACL as per strace output of nfs4_setfacl is *system.nfs4_acl.* The source code has defined it as #define NFS4ACL_XATTR_NAME ( "system.nfs4acl" ) Note there is missing underscore. After this, the EOPNOTSUPP error is not observed. Hope this helps Akash On Thu, Apr 5, 2018 at 11:43 PM, Jeremy Allison

Is nfs4acl_xattr available in any version of samba? I just upgraded to 4.9.6 but it doesn’t seem to be baked in.

Hello, I'm running a PDC and a secondary DC in privilegded lxc containers and try to setup a fileserver in an unprivileged lxc container. The shares of the file server are on the ZFS of the host and mapped via bind-mount. I've got the problem, that I get error messages when setting the ACLs of a samba share either via the Windows explorer or using the smbcacls command. On Windows

hi there - is it possible to share a directory via samba and (kernel-)nfsv4 in parallel and make samba use (ie.: read, write and enforce) nfsv4 acls to implement winnt-acls? i know that using nfs3 and posix acls is working halfway okay, but couldn't find anything useful for nfsv4 and the associated acls - sorry if i missed something obvious. i played around with the nfs4acl_xattr and

You posted: My two DC are Samba4 (migrated of the Windows 2008 Server) and my current File Servers are Windows 2008 Server.

Two attached patches for samba 2.2.7a and 3.0-alfa22, that I've made today, fix 3 bugs mentioned in my previous e-mail. 1) For each file in addition to ALLOW ACE proper DENY ACE is created. 2) "Take ownership" is shown DENIED for all except root ACEs 3) Read Permissions and read attributes are always shown as allowed, as they are actually allowed. -- Zhitomirsky

Hi Ralph Thanks a lot. With xattr_tdb I could at least list the files getting rid of access denied error. I still do not see the exactly mapped ACEs in the Security Descriptor of a file in Windows Explorer but I will debug that little further and then come back with questions. I see only 1 entry of Everyone on Windows client side if there are added ACEs using nfs4_setfacl. Let me know if that

Whenever I try to read or modify ACLs from my Windows 2000 PDC, my Samba Domain Member Server (Security = ADS) does not allow setting ACLs, nor does it display the existing ACLs. - I have setup ACLs in my Kernel - I have translated and installed libacl and libattr - I can see and modify ACLs with getfacl and setfacl. - I have translated Samba 3.0.23d with --with-acl-support=yes - I have enabled

I guess you have to patch the code, or find someone who does it for you. Iirc currently the module
