connection manager won't autoconnect if connection not shared for all users

[Jim Beam]

i have a wpa enterprise connection for my university (eduroam) and when i turn on my laptop near an eduroam AP before even logging into my account a wpa window asking for the password opens up.
to stop this i turned off "share this connection for all users" but since then it wont autoconnect to this network anymore.
