Have you got 'Available to all users' ticked for your network
connection?  Otherwise the network will not be up till after you
login.  Right click on the NM applet > Edit Connections > select the

If you can't find another solution you might like to look at WICD
rather than Network Manager.  It has the ability to specify scripts to
run after the connection comes up, so you could do your authentication
there.
