Exactly how did you reinstall? Did you recreate everything, or are you trying to reuse parts of a previous installation (e.g. /home)? Many people, including me, have upgraded from Slink to Potato without such a problem. You're not trying to use passwd and group files or /home directories left over from a previous distribution are you? --
