  NFS V4 does not mount at system start

Bug description:
  Hi,

  i'm running a view Ubuntu 18.10 Clients on a Ubuntu 18.04 NFS V4
  Server. I'm using Kerberos for user authentication and LDAP for user
  and group synchronisation.

  The shares are added to the /etc/fstab on my clients and they should be mounted automatically at system boot. Here is an example line from fstab:
  nfs.server:/users         /home             	nfs4    sec=krb5i,soft,_netdev,auto  0  0

  But after the system has booted and the Login-Screen appears the nfs
  shares are not mounted on the client. Attached to this bug, you can
  find an export of my journald entries from my last boot.

  When I read this log carefully I find the following start order of relevant services:
  Begin start nss_ldap (from line 822 on)
  Begin start NetworkManager (from line 1198) 
  Get IP from DHCP (line 2542)
  NetworkManager Online (line 2551)
  Try to mount NFS Shares (from line 2253)
  nss_ldap connected (line 2761)

  As far as I understand my setup, I do not have DNS before nss_ldap is
  started. But since mounting the NFS shares needs DNS, the NFS mount
  sequence should start after nss_ldap is fully started.

  Thanks for your help
