Title:
  kadmin: IPv6 support binds IPv4 socket leading to EAFNOSUPPORT.

Status in “krb5” package in Ubuntu:
  Fix Released
Status in “krb5” package in Debian:
  Fix Released

Bug description:
  Package: krb5-user
  Version: 1.8.3+dfsg-4
  Severity: important
  File: /usr/bin/kadmin

  Here is a small bit of strace output:
  socket(PF_INET, SOCK_STREAM, IPPROTO_TCP) = 4

  bind(4, {sa_family=AF_INET, sin_port=htons(775),
      sin_addr=inet_addr("0.0.0.0")}, 16) = 0

  connect(4, {sa_family=AF_INET6, sin6_port=htons(749),
      inet_pton(AF_INET6, "::", &sin6_addr), sin6_flowinfo=0,
      sin6_scope_id=0}, 16) = -1 EAFNOSUPPORT (Address family not supported
      by protocol)

  Obviously the bind needs to be made IPv6 aware.  I hope this is self
  explanitory, the initial connection to the admin server falis as a
  result and kadmin exits.  Also the addres in the connect seams wrong.
  This is run on localhost and the '-s 127.0.0.1' option is ignored.
