How to find out the wireless authentication mode?

Question

I'm trying to get the authentication mode (WPA/WEP) on all the available AccessPoints via DBUS API(in Linux). NetworkManager API describes a property WPAFLAGS but I don't get anything out of it (I get Null Flag everytime). D-Feet DBUS debugger also doesn't show anything. Am I missing something, or is the API broken?

Looks like you are doing something wrong:

$ dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager/AccessPoint/995 org.freedesktop.DBus.Properties.Get string:'org.freedesktop.NetworkManager.AccessPoint' string:'WpaFlags'
method return sender=:1.1188 -> dest=:1.2189 reply_serial=2
   variant       uint32 324
$ dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager/AccessPoint/994 org.freedesktop.DBus.Properties.Get string:'org.freedesktop.NetworkManager.AccessPoint' string:'WpaFlags'
method return sender=:1.1188 -> dest=:1.2190 reply_serial=2
   variant       uint32 332
$ dbus-send --print-reply --system --dest=org.freedesktop.NetworkManager /org/freedesktop/NetworkManager/AccessPoint/991 org.freedesktop.DBus.Properties.Get string:'org.freedesktop.NetworkManager.AccessPoint' string:'WpaFlags'
method return sender=:1.1188 -> dest=:1.2191 reply_serial=2
   variant       uint32 276
