I would say this is not a problem. It is up to you not to leave keyrings with confidental data unlocked when you grant someone to use your console. He can suck data from the keyring anyways, even without the keyring manager -- that's the purpose of keyring manager. (He can look into your mail client's memory if you keep it running, etc.).
That's the basic principle: *Never* let anyone who you do not trust use your desktop. Log off or lock screen when you leave the terminal. -- Lubomir Kundrak (Red Hat Security Response Team) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
