This counter counts roams within a mobility network-id that completed without AAA authentication. An admin cares because a high proportion of no-AAA roams relative to total roams may indicate open or locally authenticated clients rather than clients validated against a RADIUS server. For example, if a mobility group is supposed to enforce AAA everywhere but cwdsiRoamMblGrpStatsNoAuthAaa keeps climbing, that signals some clients are roaming through an unauthenticated path.
