I tried the above script change on a XP domain member machine and
with csih_FORCE_PRIVILEGED_USER set to yes.  It works, it's just a
bit bumpy:

  *** Info: This script plans to use 'cyg_server'.
  *** Info: 'cyg_server' will not be able to log on interactively, but will only
  *** Info: be used by registered services.

The message is incorrect.

  *** Query: Do you want to use different name? (yes/no) no
  mkpasswd (273): [2221] The user name could not be found.

I'm not sure why is mkpasswd is called here, but it's called with -l
only so it can't find the domain account.  Can this test be skipped
if the user has been directly taken from /etc/passwd?

  *** Query: Please enter the password for user 'cyg_server':
  *** Query: Reenter:


  *** Info: The sshd service has been installed under the 'cyg_server'
  [...]

Btw., there's a test for the administrators group in /etc/passwd.
This test is not necessary.  The only reason to have the admins
group in /etc/passwd is to print file ownership correctly.  It doesn't
have any other value.


Thanks,
Corinna
