How to Configure nsswitch.conf in ubuntu 18.04 (upgrading from 16.04)

Question

I am upgrading my client system from ubuntu 16.04 to ubuntu 18.04

/etc/nsswitch.conf

passwd: compat files nis nisplus

group: compat files nis nisplus

shadow: compat files nis nisplus

gshadow: files

hosts: files mdns4_minimal [NOTFOUND=return] dns myhostname

networks: files

protocols: db files

services: db files

ethers: db files

rpc: db files

netgroup: nis

In ubuntu 18.04

/etc/nsswitch.conf

passwd: compat files nis nisplus systemd

group: compat files nis nisplus systemd

shadow: compat files nis nisplus

gshadow: files

hosts: files mdns4_minimal [NOTFOUND=return] dns myhostname

networks: files

protocols: db files

services: db files

ethers: db files

rpc: db files

netgroup: nis

But now I am unable to connect to server.

I am getting the message:

A start job is running for Hold until boot process finishes up.

Kindly help.

Answer 1

In my case I run nis ( dont have nisplus) and I check local accounts first then nis. I found that compat will do the necessary with nis checking for me( perhaps nisplus as well)ie checks the + entries in /etc/passwd and check local passwd with + and override home directories shells etc. If use it in this way, I can log in from command line with both a local and nis account ( with both a local and nfs home). For some reason there is a delay of 25 seconds approximately until the shell prompt is returned. On X it times out and locks screen. So I still have difficulties, but this might point you a bit further down the road or maybe it will work for you. Id be interested if you could post if you get it working fully.
