Ubuntu HPC Create new user

Once HPC setup is done properly, to create any new user (eg user3) please use below steps:

Create user using:

useradd -m  -d  /export/home/user3 -s /bin/bash user3
passwd user3

Create SSH key and configure them as authorized using:

su - user3
ssh-keygen
cat ~/.ssh/id_rsa.pub >> ~/.ssh/authorized_keys;  chmod 600 ~/.ssh/authorized_keys

Validate key based ssh within master node using
```
su - user3
ssh user3@<masternode>
```
This should not ask password for the self ssh as user3 on master node
Update NIS database using root user on master node:
```
make -C /var/yp
```
Reboot all compute nodes
Validate user details on compute node using:
```
getent passwd user3
```
The home folder for user3 should properly show as /export/home/user3

Validate key-less SSH to compute nodes from master node using:

su - user3
ssh user3@<compute>  #This should not ask password, Do for all compute nodes

(Optionally) Run test job as explained at Ubuntu HPC Execute parallel jobs using user3.
