Nis-Options
###########

These scenarios check DHCP server NIS/NIS+ options.
NIS (Network Information Service) provides centralized authentication and configuration
management for UNIX/Linux networks. NIS+ is the enhanced version with improved security.
This includes: nis-domain (option 40), nis-server (option 41),
nisplus-domain (option 64), and nisplus-server (option 65).

***************
Test NIS-Domain
***************

Description
===========

This scenario checks the ``nis-domain`` option.
The DHCP server configures the NIS domain name, and the client receives it.
The NIS domain is used by UNIX/Linux systems for centralized authentication (Option 40).

**********************
Test NIS-Server Single
**********************

Description
===========

This scenario checks the ``nis-server`` option with a single NIS server.
The DHCP server configures one NIS server IP address, and the client receives it.
NIS servers provide centralized user/group management for UNIX networks (Option 41).

************************
Test NIS-Server Multiple
************************

Description
===========

This scenario checks the ``nis-server`` option with multiple NIS servers.
The DHCP server configures three NIS servers, and the client receives all of them.
Multiple NIS servers provide redundancy for authentication services.

*******************
Test NIS-Server VRF
*******************

Description
===========

This scenario checks the ``nis-server`` option when the DHCP server is configured with VRF.
Multiple NIS servers are configured in a VRF environment, and the client receives them correctly.

Scenario
========

.. include:: nis-options/testnis-servervrf

.. raw:: html

  <hr>

*************************
Test NIS Combined Options
*************************

Description
===========

This scenario checks NIS domain and servers configured together.
The DHCP server configures both nis-domain and multiple nis-servers.
This is the typical configuration for a UNIX network with NIS authentication.

Scenario
========

.. include:: nis-options/testniscombinedoptions

.. raw:: html

  <hr>

**********************
Test Change NIS-Domain
**********************

Description
===========

This scenario checks that the NIS domain can be changed dynamically.
Configure an initial NIS domain, then change it and verify the client receives the new value.

Scenario
========

.. include:: nis-options/testchangenis-domain

.. raw:: html

  <hr>

**********************
Test Remove NIS-Server
**********************

Description
===========

This scenario checks that NIS servers can be removed.
Configure NIS servers, then remove them and verify they are no longer sent to the client.

Scenario
========

.. include:: nis-options/testremovenis-server

.. raw:: html

  <hr>

*******************
Test NISplus-Domain
*******************

Description
===========

This scenario checks the ``nisplus-domain`` option.
The DHCP server configures the NIS+ domain name, and the client receives it.
NIS+ is the enhanced version of NIS with improved security (Option 64).

Scenario
========

.. include:: nis-options/testnisplus-domain

.. raw:: html

  <hr>

**************************
Test NISplus-Server Single
**************************

Description
===========

This scenario checks the ``nisplus-server`` option with a single NIS+ server.
The DHCP server configures one NIS+ server, and the client receives it.
NIS+ provides enhanced security over standard NIS (Option 65).

Scenario
========

****************************
Test NISplus-Server Multiple
****************************

Description
===========

This scenario checks the ``nisplus-server`` option with multiple NIS+ servers.
