NetworkManager doesn't use the supplicant configuration file, but pushes
the configuration to it over D-Bus.  However, if you look at your syslog
(/var/log/daemon.log or /var/log/NetworkManager.log) you'll see the
configuration NM is sending:

<info> Config: added 'ssid' value 'my ssid'
<info> Config: added 'scan_ssid' value '1'
<info> Config: added 'key_mgmt' value 'WPA-PSK'
<info> Config: added 'psk' value '<omitted>'
<info> Config: added 'proto' value 'WPA RSN'

which you can add to the supplicant config file inside a standard
supplicant network block, which you can see examples of here:
