# Using variables is nice
GROUP=B2006

#First we list all the teachers
for TEACHER in $(getent group teachers | cut -f4 -d: | tr "," " ") ; do
  # Then check if teacher is already a member of group $GROUP
  id $TEACHER | grep -q "($GROUP)" && continue

  # Then we create a small ldif to add the user to the group
  echo "dn: cn=$GROUP;ou=Group,dc=skole,dc=skolelinux,dc=no"
  echo "changeType: Modify"
  echo "add: MemberUid"
  echo "memberUid: $TEACHER"
  echo

  # when all is done feed everything through ldapmodify
done | ldapmodify -xWZD cn=admin,ou=People,dc=skole,dc=skolelinux,dc=no

# OK - Done
