You said you wanted to launch from the client, but here you are
launching a session in advance.
Did you mean "connect from the client" instead?

The "allow" authentication module does not use any arguments.
Certainly not the database file which is meant to be used by the sqlite
auth module.

Specifying remote hosts is documented for the sqlite backend on the
proxy wiki page:
sqlite_auth.py ./auth.sdb add foo bar nobody nobody tcp://

FYI: tcp-auth here would apply to the session you end up starting.
That's usually a bad idea for anything but testing.
And in this case, it is very unlikely to be needed since you will be
connected to the session when you start it anyway.

xpra will refuse to send password unencrypted over the network.

Like it says, use encryption.
