# This program is open source; you can redistribute it and/or modify it under the terms of the GNU General Public #
# This is an normal bash script and can be executed with sh EX: ( sudo sh ADconnection.sh ) #
# Generic user setup is: administrator, domain admins, groupnamesudores= groupname=hostname + sudoers on group name in AD groups #

#This scrips is a long serie of small updates and not well planned, the script works as expected, but this is not beautiful code #
# Maybe someday I re-do the script and make it "good code" but overall it has minimal shellcheck issues #
##################################################################################################################################
#known bugs:sometimes domain discovery fails, it can help canceling the script and re-running it, if not verify dns setting on client,
