[Bug 780820] [NEW] kadmin: IPv6 support binds IPv4 socket leading to EAFNOSUPPORT.

[Mike Mestnik]

Public bug reported:

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.
