Hello, Usually after few days, some of my user get permission revoked to where they have the permission. The issue does not affect all users and all clients at the same time. As instance an user can have access granted on host1 but permission denied on host2, Moreover an user1 can have all his permission working properly, while another user2 get his permission revoked on the same host. After a reboot usually everything work fine for all users. It seems that the user are not map anymore to the right one because, the user can read directory with "755 but not private one, i.e. with 700. Moreover he still have write permission on at less some directory with "755". What I can do to fix this issue without annoying user that have correct permission ? I tried to restart nfs-client, nfs-server, rpc-nfsidmap, winbind, gssproxy without success. Thanks by advance
