I've setup my external drives in crypttab with a specified keyfile. But when decrypting/mounting these drives via dolphin, i get the password dialoge. Everything else (mapping, mountpoint) in crypttab and fstab seems to be respected (besides https://bugs.kde.org/show_bug.cgi?id=402693 ), so i would assume that a keyfile-entry should work, too? My syntax should be OK - my internal drives are decrypted and mounted properly on boot, only difference is the "noauto"-option.
