- add upstream patches to fix standalone kpropd exiting if the per-client
  child process exits with an error (MITKRB5-SA-2011-001), and a hang or
  crash in the KDC when using the LDAP kdb backend (MITKRB5-SA-2011-002)
  (CVE-2010-4022, #664009, CVE-2011-0281, #668719, CVE-2011-0282, #668726)

* Thu Sep 23 2010 Nalin Dahyabhai <nalin@redhat.com> 1.7.1-15
- make -libs actually own /usr/kerberos, because it may be the only reason
  that directory exists, due to owning /usr/kerberos/share (#636746)
* Mon Sep 13 2010 Nalin Dahyabhai <nalin@redhat.com> 1.7.1-14

  wrong error table but subsequently attempt to unload the right one
* Wed Jun  9 2010 Nalin Dahyabhai <nalin@redhat.com> - 1.7.1-11
- use the "pathmunge" function to add %{krb5prefix}/bin to $PATH rather
  than doing it the harder way ourselves (part of #544652)
* Thu May 27 2010 Nalin Dahyabhai <nalin@redhat.com>
- ksu: move session management calls to before we drop privileges, like
  su does (#596887), and don't skip the PAM account check for root or the
  same user (more of #540769)
* Tue May 18 2010 Nalin Dahyabhai <nalin@redhat.com> 1.7.1-10
- add patch to correct GSSAPI library null pointer dereference which could be
  triggered by malformed client requests (CVE-2010-1321, #582466)
