linbo-remote strips school from hostname

[PLanB2008]

MacAddress cant be determined in this case...

Hence get_mac uses ldbsearch this seems to be wrong:

# get host's mac address from AD
# get_mac <ip|hostname|mac>
get_mac(){
  local attr="sophomorixComputerMAC"
  if validip "$1"; then
    $LDBSEARCH "(sophomorixComputerIP=$1)" $attr | grep ^$attr | awk '{print $2}'
  elif validhostname "$1"; then
    $LDBSEARCH "(sophomorixDnsNodename=$(tolower $1))" $attr | grep ^$attr | awk '{print $2}'
  elif validmac "$1"; then
    $LDBSEARCH "($attr=$(toupper $1))" $attr | grep ^$attr | awk '{print $2}'
  else
    return 1
  fi
}
