Tried this, but did not quite succeed. The problem is that this would 
require entries for every single user. But the following auto.home then 
worked for me:

#!/bin/bash
FIRST_LETTER=`echo $1|cut -c 1`
echo server:/prefix/homestore_${FIRST_LETTER}/$1

This returns the correct path.

In auto_master they have a line "/level1 auto_level1", then in 
auto_level1, there is "level2 -fstype=autofs auto_level2", this is what 
I mean with cascading. Meanwhile, I found another Linux box here which 
does the same, but the syntax is different: "level2 -fstype=autofs 
file:/full/path/to/map"
