GRRRR login/out sound

[Nils]

Hello,

I just installed Dapper beta on my laptop and saw that there is still
a problem with the login / logout sound.

After logging in in System > Preferences > Sound I chose "No sound"
for login and logout. But when I logged in next time I still hear that
sound.

These windows like login / logout sounds are especially annying when
you are at school or on a meeting. I'm not sure, but I think I read
somewhere that this should be disabled in Dapper by default. (which
would make sense, since Dapper is for enterprises)

Please make sure that you are at least able to disable them if you want.

Regards

Nils
