Allow user namespace friendly connection?

Similarly to https://gitlab.freedesktop.org/dbus/dbus-python/-/issues/46, https://gitlab.freedesktop.org/dbus/dbus/-/issues/195 or systemd/systemd#11785, it seems that zbus always sends user id when connecting to server, which prevent its use from a namespaced context.

Is there a way to make Auth/External requests without putting the uid (or with an empty parameter, not very clear for me what is really needed for this to work) ?

Thanks in advance for your help.

Thanks for filing this. I would not have any objections to adding this.

I'm very confident this is going to fairly trivial. Mostly it should be about add a nice API to set the last parameter to None here.

Hello,
We tried putting None for the last parameter (without the nice API ;)), but this triggers another issue : “Error: ZBus(Handshake("Missing DATA data"))”.
It seems that in this case there is a supplemental "DATA" empty answer from server that has to be replied (as explained here : systemd/systemd@1ed4723).

Ah ok, not super trivial then. 😄
