[Bug 1088682] Re: dhclient does not register hostname to dynamic DNS (AD)

[Launchpad Bug Tracker]

This bug was fixed in the package isc-dhcp - 4.2.4-4ubuntu1

---------------
isc-dhcp (4.2.4-4ubuntu1) raring; urgency=low

  * Merge from Debian, remaining changes:
    - Apparmor profiles for dhclient and dhcpd.
    - Upstart jobs for isc-dhcp-server, isc-dhcp-server6, isc-dhcp-relay and
      isc-dhcp-relay6. (LP: #944849)
    - Separate default file for isc-dhcp-relay6. (LP: #944849)
    - Apport hook for isc-dhcp-client and isc-dhcp-server.
    - dhclient.conf: Set for IPv6 (dhcp6.*) (LP: #770324)
    - If /etc/ltsp/dhcpd.conf exists, use that instead of /etc/dhcp/dhcpd.conf
    - Drop isc-dhcp-server/new_auth_behavior question from high to medium
    - Create user/group dhcpd (LP: #727837)
    - Create /etc/dhcp/ddns-keys/ for DDNS updates (LP: #341817)
    - Build with extra hardening and use --enable-paranoia to run dhcpd as user
      (LP: #727837)
    - Add IPv6 support to dhclient-script.linux.udeb
    - Wait for /etc/resolv.conf to be writable in dhclient-script.linux.
      (LP: #856984)
    - Sanitize environment in dhclient-script.linux. (LP: #1045986)
    - Don't call 'ip addr flush' as it breaks IPv6 networking. (LP: #1023174)
    - debian/apparmor-profile.dhclient: update to add the new paths used by
      NetworkManager for its conf and leases files; standardized under
      /var/lib/NetworkManager.
    - Remaining Ubuntu patches:
      + dhclient-fix-backoff
      + dhclient-more-debug (LP: #35265)
      + dhclient-safer-timeout (LP: #838968)
      + dhcpd.conf-subnet-examples (LP: #26661)
      + multi-ip-addr-per-if (LP: #717166)
      + onetry_retry_after_initial_success (LP: #974284)
      + revert-next-server
    - Dropped Ubuntu patches:
      + dhclient-onetry-call-clientscript (now in Debian)
  * Fix isc-dhcp-server-ldap not actually containing ldap support.
    Thanks to Christian Hoffmann for tracking down the issue. (LP: #1071928)
  * Don't set fqdn.fqdn in dhclient.conf as that seems to confuse some DHCP
    servers. An alternative would have been to only set fqdn.fqdn and not
    host-name, but that appears to confuse another set of servers.
    For now go with just host-name which is the most common and if becomes a
    big problem for IPv6 (where fqdn.fqdn is apparently required), then we'll
    need to have a separate dhclient6.conf file and change all the calls to
    dhclient -6 to use that file instead. (LP: #1088682)
  * Include patch from RedHat/Fedora to deal with hardware/xen/virtio offload
    of UDP checksums. (LP: #930962)

isc-dhcp (4.2.4-4) unstable; urgency=medium

  * Run exit hooks when "dhclient -1" fails (closes: #486520).
  * Add dhcp6.name-servers and dhcp6.domain-search to the default request
    options in dhclient.conf (closes: #693315).

Title:
  dhclient does not register hostname to dynamic DNS (AD)

Status in “isc-dhcp” package in Ubuntu:
  Fix Released
Status in “isc-dhcp” source package in Quantal:
  New
Status in “isc-dhcp” source package in Raring:
  Fix Released

Bug description:
  This is not working in quantal (4.2.4-1ubuntu10) and raring
  (4.2.4-3ubuntu1), but is working in precise (4.1.ESV-R4-0ubuntu5).

  A patch fixed an issue for bug 991360 where dhclient.conf was amended to include:
  send fqdn.fqdn = gethostname();

  This causes failures when the client tries to register was some DHCP servers (for example Windows AD DDNS servers).
  By commenting out this line and restarting the client, the client can then register with this type of DHCP server.

  However, this is needed to ensure dhcpv6 works.
