mounting DFS filesystem with remote shares in it on Arch Linux

Solution 1:

Last time I've got this error on Ubuntu 16.04.6 file server with Samba packages updated automatically in April to 4.3.11+dfsg-0ubuntu0.16.04.19. Win10 clients stops authenticating with server and the similar error message (Failed to find cifs/[email protected](kvno x) in keytab MEMORY:cifs_srv_keytab (aes256-cts-hmac-sha1-96) in Samba server log. My setup have a lot common with yours, one Server 2016 AD DC, Ubuntu 16.04.6 Samba NAS, Windows clients. Difference in error is that in my case was listed my file server instead of DC in your case. Solved by downgrading Samba packages on NAS to previuos version (4.3.11+dfsg-0ubuntu0.16.04.17).

Seems that you have to at least try to check update log for Samba components, first on NAS and then laptop and check if downgrading them to previous versions will solve the problem.
