For the record, I couldn't make it a work in a more elegant way, so here's
the "quick and dirty" solution (using the internal DNS server). I run this
script every 10 minutes or so via cron.
This updates the record for "www.foo.com" considering the AD domain is "
foo.com" and the webserver "www.foo.com" is hosted externally. dc1 is the
domain controller, 22.214.171.124 in this case is Google DNS servers:
WWW_CURRENT=`dig @localhost www.foo.com A +short | tail -n1`
WWW_NEW=`dig @126.96.36.199 www.foo.com A +short | tail -n1`
if [ $WWW_CURRENT != $WWW_NEW ] && [ ! -z $WWW_NEW ]
/usr/local/samba/bin/samba-tool dns update dc1 foo.com www A
$WWW_CURRENT $WWW_NEW --password=adminpassword
