Title:
  Mounting SOFS SMB shares fails

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Ubuntu 18.04.1 LTS 4.15.0-33.36-generic
  cifs-utils 2:6.8-1

  Mounting scale-out SMB shares is failing.

  mount -t cifs -o 
credentials=/tmp/creds,domain=cbs.com,uid=114,gid=119,vers=3.0,_netdev,nodfs 
//s2dscaleout.cbs.com/glance-images /tmp/test_mount
  mount error(5): Input/output error
  Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

  What works:
  * mounting the share from a 16.04 host
  * mounting standalone smb3 shares

  Relevant error from the log (full logs attached separately):
