| [[https://wiki.gnome.org/Projects/NetworkManager|Network Manager]] version 1.12 integrated a basic IWD-based wifi backend as an alternative to wpa_supplicant. To use Network Manager (NM) with the IWD backend one NM configuration change is necessary. Additionally the versions of the two software packages need to be compatible, this is because IWD's API and capabilities are evolving and the NM backend is adapting to those changes. IWD and the NM backend are work in progress and the capabilities are still limited. | [[https://wiki.gnome.org/Projects/NetworkManager|Network Manager]] version 1.12 integrated a basic IWD-based wifi backend as an alternative to wpa_supplicant.

| + | //(Since 1.30)// Selects between IWD-driven (when ''yes'', default) or NM-driven (when ''no'') autoconnect logic: | ||

| + | |||
| + | //(Currently in master, to arrive in 1.32 or 1.34)// Tells NM to re-write IWD network configurations whenever an NM network profile is changed thus enabling editing settings such as EAP authentication from //nm-connection-editor// GUI. With IWD versions 1.15 and later this is on by default (set to ''no'' or an empty string to disable). With IWD versions 1.14 you must specify a valid path (''iwd-config-path=/var/lib/iwd'') to enable. //Warning:// when enabled NM profiles are the authoritative ones and IWD's ''/var/lib/iwd'' files can get overwritten any time: | ||

| The NM-side profile for the 802.1X network should match the settings stored in the IWD provisioning file for given network, as closely as possible, but using the standard NM settings sytntax (''**nm-settings**(5)'', ''**nm-settings-keyfile**(5)'') -- this will allow the NM clients to ask users for the right secrets during a connection attempt, if any secrets are required. If no connection-time secrets are needed, e.g. because they're provided in the provisioning file already, then the NM profile can have any settings in it -- the profile will not be used by IWD, it only tells NM that given network is known and connectable. | The NM-side profile for the 802.1X network should match the settings stored in the IWD provisioning file for given network, as closely as possible, but using the standard NM settings sytntax (''**nm-settings**(5)'', ''**nm-settings-keyfile**(5)'') -- this will allow the NM clients to ask users for the right secrets during a connection attempt, if any secrets are required.
