run script after connection is established

Hi,

i wonder if its possible to let NetworkManager run a script after it
successfully established a connection to a WLAN. i'm required to login
at a intranet website before being able to access the internet. so i
would like NetworkManager to run a script that does the login for me
when i'm connected to that ESSID.
