you need access to a random shell of that user (what does not imply you actively logged into it), but can expose another session that pot. allows access to other logins (mail, webservices, even banking) this should (by default) no way be possible. any way to circumvent authentication to this very session should be guarded by a special "knowwhatido" key or require active authentication (ie. passing the pass hash via dbus - what's insecure enough by itself) - Thomas ----------------------------------------------------------- This is an automatically generated e-mail.
