# Authentication and authorization and IETF NACM
# NACM module rules
# @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
# not yet implemented
# Tests for
# deny-ncm: This rule prevents the "guest" group from reading any
# monitoring information in the "ietf-netconf-monitoring" YANG
# module.
# permit-ncm: This rule allows the "limited" group to read the
# "ietf-netconf-monitoring" YANG module.
# permit-exec: This rule allows the "limited" group to invoke any
# protocol operation supported by the server.
# permit-all: This rule allows the "admin" group complete access to
# all content in the server. No subsequent rule will match for the
# "admin" group because of this module rule
