Bug description:
  Got pinged about this, not fixed in 12.04 yet. From the Redhat bug:

  "We have verified that getaddrinfo() does reverse address calls to DNS
  when AI_CANONNAME is passed in hints.ai_flags and returns the PTR name
  of the forward resolved ip address as Canonical name.

  The canonical name is arguably not what is returned by the PTR record
  for various reasons. Aside the fact that PTR record are often not
  under control of the the same people that control the A name, A names
  can also be roundrobin names and return multiple addresses. Picking
  one and returnings its PTR as canonical name seem highly questionable.

  A CNAME -> A name resolution is welcome as the A name is arguably the
  Canonical name of a CNAME. But getaddrinfo shouldn't do PTR requests
  to the DNS.

  We found this when testing ssh+GSSAPI auth on laptops that can properly set the A record for their name usin dynamic DNS updates but cannot change the PTR record of whatever network they are currently travelling in.
  This breaks kerberos which needs the canonical (A record) name to construct the principal name used to request a ticket when rdns = false is set in krb5.conf and GSSAPITrustDNS is set to no in ssh (the default)."
