  Mounting an SMB share with
  
sec=ntlmssp,vers=3.0,credentials=/home/.smbcredentials,dir_mode=0777,file_mode=0777
  
  in /etc/fstab gives the error: "CIFS VFS: ioctl error in
  smb2_get_dfs_refer rc=-2" in dmesg.
  
  Shares mounted this way are readable, but writing data to them (or using
  programs such as EasyTAG to write to them) ultimately fails. This bug
  did not occur in kernel 4.10. Mounting the share(s) with vers=1.0 does
  not give the error, but this is a haphazard fix as SMB v3.0 carries many
- security features with it.
+ security features with it not avaliable in SMB 1.0.
