-/* The idea here is to be able to run mate-screensaver-dialog without any setuid bits.
- * Password verification happens through an external program that you feed
- * your password to on stdin. The external command is invoked with a user
- * name argument.
- *
- * The external helper does whatever authentication is necessary. Currently,
- * SuSE uses "unix2_chkpwd", which is a variation of "unix_chkpwd" from the
- * PAM distribution.
- *
- * Normally, the password helper should just authenticate the calling user
- * (i.e. based on the caller's real uid). This is in order to prevent
- * brute-forcing passwords in a shadow environment. A less restrictive
- * approach would be to allow verifying other passwords as well, but always
- * with a 2 second delay or so. (Not sure what SuSE's "unix2_chkpwd"
- * currently does.)
