Take 2: Testers for new ssh-*-config scripts wanted!

Hi,
I'd like to ask for more testing of the new ssh-host-config and
ssh-user-config scripts.
The new thing here is, that the ssh-host-config script now tries to
figure out if the machine is a 2003 Server or newer system. If so,
the script asks, if it should create a new account "sshd_server"
to use as account to run sshd as service under. If you say "yes" at
this point, a bunch of funny new activities is started:
- The script creates a sshd_server account
- It adds that account to the administrators group *iff* it's able
to figure out the name of that group from the /etc/group file.
This means, you must not change the name of the administrators
group in /etc/group and the SID (S-1-5-32-544) must be available
in that entry.
- It uses the new editrights utility to add the necessary user rights
to the new sshd_server account.
These rights also explicitely deny logon locally and over network
and allow logon only as service for security reasons.
The ssh-user-config script has also been changed. It tries to
figure out if the machine is a 2003 Server or newer and if so, it
sets the permissions of the users ~/.ssh directory and the users
~/ssh/authorized_keys file so that the sshd_server account has read
permissions on both. If it's an older system, it does the same for
the SYSTEM account.
Also on 2003, the sshd_server account is used for ownership of the
important files (/etc/ssh*, /var/empty, /var/log/sshd.log).
Further changes:
- Require bash for both scripts.
- Use `read -e' in both scripts to enable readline support.
So, I'd like to ask especially users of a 2003 Server system to test
that script. Users of other systems are of course also welcome since
I want to be sure that I haven't broken these systems.
Attached are both scripts plus the vanilla ssh_config and sshd_config
file. The latter two have to be copied to /etc/defaults/etc. Please
not that the "editrights" tool has to be installed on your system.
You can find it in the Base category when updating with setup.exe.
Thanks in advance,
Corinna

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.
# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.
# Site-wide defaults for various options
# Host *
# ForwardAgent no
# ForwardX11 no
# RhostsRSAAuthentication no
# RSAAuthentication yes
# PasswordAuthentication yes
# HostbasedAuthentication no
# BatchMode no
# CheckHostIP yes
# AddressFamily any

# This is the sshd server system-wide configuration file. See

# This sshd was compiled with PATH=/usr/bin:/bin:/usr/sbin:/sbin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
