# Authentication and authorization and IETF NACM

|
# NACM module rules
|
|
# A module rule has the "module-name" leaf set but no nodes from the
|
|
# "rule-type" choice set.
|
|
# @see test_nacm.sh is slightly modified - this follows the RFC more closely
|
|
# See RFC 8341 A.1 and A.2
|
|
# Note: use clixon-example instead of ietf-netconf-monitoring since the latter is
|
|
# A) Three tracks in the code for leaf/leaf-list, container/lists, and root
|
|
# B) Three operations: create, update, delete (write)
|
|
# C) Two access operations: permit, deny (also default deny/permit)
|
|
# This gives 18 testcases
|
|
# Set group access:
|
|
# - Admin: permit: create, update, delete
|
|
# - Limit: permit: create, delete; deny: update
|
|
# - Guest: permit: update; deny: create delete
|
|
# ops\track:| root | leaf | list
