Can you share your nss_ldap configuration, as well as /var/log/syslog
and /var/log/auth.log? And, just to confirm, your sshd user is NOT in
ldap, right?

Title:
  systemd script for sshd allows it to start too early should wait for
  authentication services...

Status in cloud-init package in Ubuntu:
  Incomplete
Status in openssh package in Ubuntu:
  Incomplete

Bug description:
  After the most recent update to 16.04 I found that sshd failed to
  launch on bootup. On my particular system this is because it was not
  able to authenticate the user 'sshd'. It appears to be because it is
  starting before authentication services are completely available on my
  system. A simple fix was to make the following change to
  /lib/systemd/system/ssh.service:

  --After=network.target auditd.service
  ++After=network.target auditd.service accounts-daemon.service

  Starting too early might be a security issue, but I do not have the
  expertise to make that judgment. This may also be related to and solve
  this bug #1024475 as I am also serving some of my accounts from ldap.
