How to Create a user using Freeipa

Prerequisites:

1. Make sure the server and client are installed
2. The admin user has to be initialized using kerberos authentication.

kinit admin (When prompted provide the password)

##Adding the New User

1. ssh to manager node

ssh xxxxx@192.168.1.5

1. Use the command below to create a user:

`ipa user-add '' --first=''

--last='<User's last name>' --homedir='Home Directory path (optional)' 
--random`

1. The output will display the random password set. ``` "----------------------", "Added user \"omniauser\"", "----------------------", " User login: omniauser", " First name: omnia", " Last name: user", " Full name: omnia user", " Display name: omnia user", " Initials: ou", " Home directory: /home/omniauser", " GECOS: omnia user", " Login shell: /bin/sh", " Principal name: omniauser@MYIPA.TEST", " Principal alias: omniauser@MYIPA.TEST", " User password expiration: 20210804180355Z", " Email address: omniauser@myipa.test", " Random password: 0Qr:Ir;:q_vFKP+*b|0)0D", " UID: 893800014", " GID: 893800014", " Password: True", " Member of groups: ipausers", " Kerberos keys available: True"

```

1. The random password displayed can be used to login to the login node using the newly created user.

ssh omniauser@192.168.1.6

1. Change the password on first login and then login with the new password.

2. To assign permissions to the newly created user to execute slurm jobs run the command:

usermod -a -G slurm 'new_login_user'

1. The user has been assigned appropriate permissions to execute slurm jobs. Jobs can be executed

srun --nodes 1 --ntasks-per-node 1 --partition normal hostname
