[Samba] XP Pro password changing and popups

[Michal Kurowski]

Hi,

I'm not sure how it's exactly done but XP Pro seems to block
winpopups during ctrl-alt-delete session (changing passwords,
workstation locking, etc) somehow.

I'd like to prevent people from password changing trials and 
send them a popup like this:

smb.conf:

passwd program = my_script %m

my_script:

#!/bin/sh

echo "Please log to 'some machine' to change your password" | \
smbclient -M $* 

The script works OK but not when ii is actually needed. Samba
doesn't fire it up or Windows machines block it. I wonder how to 
make it work.

Ideas ?
