Merge pull request slicer69#10 from tuxillo/patch-2

Update to fix uid for non-root users.

been set in the doas.conf file) then we do not need to redirect a password

when the user authenticates with "nopass" set.

Introduced Linux support

Fixed bad password bug

Removed unused code, fixed parse.y typo

Port corresponding to upstream 5.9
