Doc Text:	A flaw was found in nmcli, where the command-line interface to the NetworkManager did not accept the 802-1x.ca-path and 802-1x.phase2-ca-path settings when creating a new profile. When a user connects to a network using this profile, the authentication does not happen and an insecure connection occurs.	Story Points:	---

Description msiddiqu 2020-05-28 08:28:13 UTC

The ifcfg-rh settings plugin does not handle the 802-1x.ca-path and 802-1x.phase2-ca-path settings. When a user uses nmcli to configure a profile, it seemingly succeeds, while the modification gets silently lost leaving the connection unauthenticated.
