This works with gawk:
#! /bin/sh
# $OpenLDAP: pkg/ldap/tests/scripts/acfilter.sh,v 1.13 2008/01/07 23:20:16

grep -v '^#' | awk 'BEGIN{FS="\n";RS=""}
  {j=0;
   for (i=1; i<=NF; i++){
     if ($i ~ /^ /){
       x[j] = x[j] "\n" $i;
     } else {
       j++; x[j] = $i
     }
   }
   print x[1];
   delete x[1];
   j=asort(x);
   for (i=1; i<=j; i++){
     print x[i];
   }
   delete x;
   print ""
  }'

(all as a single line of text)

Unfortunately the asort() function is a GNU extension, so I think we have to 
pipe to the sort command instead:

grep -v '^#' | awk 'BEGIN{FS="\n";RS=""}{j=0; for (i=1; i<=NF; i++){ if ($i ~ 
/^ /) { x[j] = x[j] "\n" $i; } else { j++; x[j] = $i }} print x[1]; for (i=2; 
i<=j; i++){print x[i] | "sort +0";} delete x; close("sort +0"); print ""}'
