Server: Debian 8, Clients: some Windows and some Xubuntu 16.04
Since I updated one Xubuntu Client to 4.13.0-26, I can't mount the samba shares.
[20390.135208] No dialect specified on mount. Default has changed to a more secure dialect, SMB2.1 or later (e.g. SMB3), from CIFS (SMB1). To use the less secure SMB1 dialect to access old servers which do not support SMB3 (or SMB2.1) specify vers=1.0 on mount.
[20390.161744] CIFS VFS: protocol revalidation - security settings mismatch

[20390.163395] CIFS VFS: cifs_mount failed w/return code = -5
I understand that is has to do with smb-Protokoll, but when I use
testparm -v | grep protocol
on my server it sais:

As far as I understand does the server have SMB2 and SMB3 support. I tried this addition in
[home]
min protocol = SMB2
respectively
[home]
min protocol = SMB3
Than I can see in server:
server max protocol = SMB3
server min protocol = SMB3
respectively
server max protocol = SMB3
server min protocol = SMB2
But the client still can't mount.
this is the part of the client's fstab:
//192.168.0.251/firmendaten /home/username/server/firmendaten cifs gid=1000,uid=1000,file_mode=0660,dir_mode=0770,user,noauto,credentials=/home/username/.smbcredentials
How can I mount using the secure protocol SMB2 / SMB3?
Thanks in advance!
