Yang data model for TACACS+
draft-ietf-opsawg-tacacs-yang-08
Abstract
This document defines a TACACS+ client YANG module, that augments the
System Management data model, defined in RFC 7317, to allow devices
to make use of TACACS+ servers for centralized Authentication,
Authorization and Accounting.
The YANG module in this document conforms to the Network Management
Datastore Architecture (NMDA) defined in RFC 8342.

1. Introduction
This document defines a YANG module that augments the System
Management data model defined in the [RFC7317] to support the
configuration and management of TACACS+ clients.
TACACS+ [I-D.ietf-opsawg-tacacs] provides device administration for
routers, network access servers and other networked devices via one
or more centralized servers.
The System Management Model [RFC7317] defines separate functionality
to support local and RADIUS authentication:
o User Authentication Model: Defines a list of usernames with
associated passwords and a configuration leaf to decide the order
in which local or RADIUS authentication is used.
o RADIUS Client Model: Defines a list of RADIUS servers used by a
device for centralized user authentication.
The System Management Model is augmented with the TACACS+ YANG module
defined in this document to allow the use of TACACS+ servers as an
alternative to RADIUS servers or local user configuration.
The YANG module can be used with network management protocols such as
NETCONF[RFC6241].
