It's not finding UID and GID in the passwd/group files, perhaps you're using yellow pages (NIS) for the users and groups?

If so you may need to fetch the group and passwd files from NIS first:
Code:
#!/bin/sh
cp /etc/group /tmp/lan.group.$$
ypcat group >> /tmp/lan.group.$$
cp /etc/passwd /tmp/lan.passwd.$$
ypcat passwd >> /tmp/lan.passwd.$$
ls -n $@ | awk 'function max(a,b) {return a>b?a:b}
function toend(str,fld)
{ for(i=0; i<length(str); i++) {
    while(substr(str,i,1) != " " && i<length(str)) i++
    while(substr(str,i,1) == " " && i<length(str)) i++
    if (!--fld) return substr(str,i)
  }
  return ""
}
FNR==1 {file++}
file==1 {g[$3]=$1;GW=max(GW,length($1));next}
file==2 {p[$3]=$1;PW=max(PW,length($1));next}
{ split($0, L, " ")
  printf "%10s %3s %-*s %-*s %11s %s\n", L[1], L[2], PW, p[L[3]], GW, g[L[4]], L
[5], toend($0,5)
}' /tmp/lan.group.$$ /tmp/lan.passwd.$$ -
rm /tmp/lan.group.$$ /tmp/lan.passwd.$$
