Thanks you very much for your help ! First, a little question. Since I encounter this bug in Debian Stretch, and as the bug behavior slightly change since the last Debian stable security update ( see CVE-2017-14604 ). Do you think it's better to report the bug on Debian's BTS first ?
Next I investigated further following you advice. Just to simplify. Say : -> /dns/parent is a parent directory -> It contain two folders : "Share" and "Ressource" that are NFSv4 referrals -> The "teachers" group have RWX access on both with ALCs. But the teacher group is not present in the standard posix permissions. Say I'm a teacher. 1) At start "gio info" say that I don't have write access to "Ressource" nom d'affichage : Ressource nom d'édition : Ressource nom : Ressource type : directory taille : 4096 uri : file:///dnfs/parent/Ressource attributs : standard::type: 2 standard::name: Ressource standard::display-name: Ressource standard::edit-name: Ressource standard::copy-name: Ressource standard::icon: folder standard::content-type: inode/directory standard::fast-content-type: inode/directory standard::size: 4096 standard::allocated-size: 4096 standard::symbolic-icon: folder-symbolic, folder etag::value: 1538394987:592109 id::file: l38:1839867 id::filesystem: l38 access::can-read: FALSE access::can-write: FALSE access::can-execute: FALSE access::can-delete: FALSE access::can-trash: FALSE access::can-rename: FALSE time::modified: 1538394987 time::modified-usec: 592109 time::access: 1538395042 time::access-usec: 749090 time::changed: 1538394987 time::changed-usec: 592109 unix::device: 38 unix::inode: 1839867 unix::mode: 17400 unix::nlink: 3 unix::uid: 0 unix::gid: 5000006 unix::rdev: 0 unix::block-size: 32768 unix::blocks: 8 owner::user: root owner::user-real: root owner::group: 2de9 2) When I traverse inside /dns/parent with Nautilus. It do some sort of file request as the two NFS referrals are mounted ( normally, from terminal, they are mounted only when you enter them ). There is two cross displayed on each folder like as I can't enter them. But "gio test" give now that I have RWX access ! And a new line at the end seems to show that Nautilus support NFSv4 ACLs ! Stunning ! I don't know this feature ! nom d'affichage : Ressource nom d'édition : Ressource nom : Ressource type : directory taille : 4096 uri : file:///dnfs/parent/Ressource attributs : standard::type: 2 standard::name: Ressource standard::display-name: Ressource standard::edit-name: Ressource standard::copy-name: Ressource standard::icon: folder standard::content-type: inode/directory standard::fast-content-type: inode/directory standard::size: 4096 standard::allocated-size: 4096 standard::symbolic-icon: folder-symbolic, folder etag::value: 1538394987:592109 id::file: l37:23199783 id::filesystem: l37 access::can-read: TRUE access::can-write: TRUE access::can-execute: TRUE access::can-delete: FALSE access::can-trash: FALSE access::can-rename: FALSE time::modified: 1538394987 time::modified-usec: 592109 time::access: 1538395042 time::access-usec: 749090 time::changed: 1538394987 time::changed-usec: 592109 unix::device: 37 unix::inode: 23199783 unix::mode: 17400 unix::nlink: 3 unix::uid: 0 unix::gid: 5000006 unix::rdev: 0 unix::block-size: 32768 unix::blocks: 8 unix::is-mountpoint: TRUE owner::user: root owner::user-real: root owner::group: 2de9 xattr-sys::system.nfs4_acl: 3) From there. The output of "gio test" will not change. I can enter the "Ressource" directory ( even with the cross ) but inside I can't create directories. 4) To solve the problem I have three possibilities : -> I can press F5 inside the "Ressource" folder. -> If I press F5 before entering the "Ressource" folder the crosses disappears. And when I enter the "Ressource" folder I can create directories inside it. -> If from any manner I go a second time inside the "Parent" folder. The crosses disappears and I can create directories inside the "Ressource" folder. It's seems that Nautilus rightly handle the rights even with nfs4 ACLs. But they are not updated on the right time. Thanks again ! This problem is very disappointing for my teachers. Baptiste.
