Hi,


if you look at
https://cgit.freedesktop.org/NetworkManager/NetworkManager/tree/clients/cli/devices.c?id=94200b03fe483f9d0df87483fa2f30301e2b9f31#n3258
you'll see, that the password is ignored by nmcli in case the AP has no
security.

Whether that is a bug or intended behavior, is up for discussion. Why
would it be better to error out in this case?


On an unrelated note: since you are using `nmcli device wifi connect`,
have a look at
https://github.com/NetworkManager/NetworkManager/pull/137
would that change be a problem for you? Or desired?



best,
Thomas
