Dear all, I am encountering problems which seems to be the description of bug 93891 - NFS access not revoked on kdestroy, https://bugzilla.kernel.org/show_bug.cgi?id=93891 Data shared over NFS in kerberos security mode are still accessible after kdestroy is issued or kerberos ticket expires. Only unmount+mount or server client reboot are working, which is not an option in our environment (tons of shares, people sharing computers etc.). Strangely, the bug seems to be very old and important, so I would suppose it is already resolved and there is some configuration option to solve this, which I am missing. Host servers are Proxmox (equals roughly to Debian 12 for now, but they have its own kernel versions) and Ubuntu 22/24 LTS, clients are mostly Ubuntu 20/22/24 LTS, but tested also on Fedora 40, all have the same problem. It makes no difference if I use gssproxy or the more traditional way of kerberos support in NFS, if the kerberos cache is in KCM or in files on disk, still the same. Is there any recommendation how to overcome this ? Thank you for any advice. Sincerely, David Komanek
