He actually meant the wpa_supplicant configuration file, not the
supplicant's dbus config file.  But when driven by NetworkManager, there
is no supplicant configuration file.

Instead, you can find out what config NM is pushing to the supplicant by
checking the NetworkManager logs, where NM will log lines like:

NetworkManager[1163]: <info>  (wlp4s0): Activation: (wifi) connection
'homewifi' has security, and secrets exist.  No new secrets needed.
NetworkManager[1163]: <info>  Config: added 'ssid' value 'homewifi'
NetworkManager[1163]: <info>  Config: added 'scan_ssid' value '1'
NetworkManager[1163]: <info>  Config: added 'key_mgmt' value 'WPA-PSK'
NetworkManager[1163]: <info>  Config: added 'psk' value '<omitted>'
NetworkManager[1163]: <info>  Config: added 'proto' value 'WPA RSN'
NetworkManager[1163]: <info>  Config: set interface ap_scan to 1

That is almost exactly what would be in the wpa_supplicant config file.
Can you grab this info from your machine for Julien?
