Unassigning: there's work needed to be done upstream, that's been being thought of for a while now, but not yet implemented; to avoid asking for the password repeatedly.
NetworkManager by itself won't go on a new network you've never connected to before and ask for the password; this may happen only when roaming to a similarly named network that has different security settings. Unfortunately, figuring out that this is the case isn't simple.
As another possibility, if you've already been on that network and you think the password is the same, maybe there was an issue migrating GConf keys from 0.8 to 0.9 in Oneiric. You may want to try setting "Available to all users" on that connection if it's not already set.
Since there's rather important changes needed to implement this upstream, I'll unassign myself and we'll revisit this issue after Precise.
