--------------------------------------------------------------------------------
ChangeLog:

* Fri Jun  1 2012 Nalin Dahyabhai <nalin at redhat.com> 1.9.3-2
- pull up the patch to correct a possible NULL pointer dereference in
  kadmind (CVE-2012-1013, #827598)
* Mon May  7 2012 Nalin Dahyabhai <nalin at redhat.com>
- skip the setfscreatecon() if fopen() is passed "rb" as the open mode (part
  of #819115)
* Thu Mar  8 2012 Nalin Dahyabhai <nalin at redhat.com> 1.9.3-1
- update to 1.9.3
  - drop patch for CVE-2011-1530, incorporated upstream
  - drop patch for #756139, incorporated into 1.9 as RT#7007
- when removing -workstation, remove our files from the info index while
  the file is still there, in %preun, rather than %postun, and use the
  compressed file's name (#801035)
* Mon Jan 30 2012 Nalin Dahyabhai <nalin at redhat.com> 1.9.2-6
- add patch to accept keytab entries with vno==0 as matches when we're
  searching for an entry with a specific name/kvno (#230382/#782211,RT#3349)
* Tue Dec 13 2011 Nalin Dahyabhai <nalin at redhat.com> 1.9.2-5
- backport patch for RT#7046: tag a ccache containing credentials obtained via
  S4U2Proxy with the principal name of the proxying principal (part of #761317)
  so that the default principal name can be set to that of the client for which
  it is proxying, which results in the ccache looking more normal to consumers
  of the ccache that don't care that there's proxying going on
- pull in patch for RT#7047: allow tickets obtained via S4U2Proxy to be cached
  (more of #761317)
- backport patch for RT#7048: allow PAC verification to only bother trying to
  verify the signature with keys that it's given (still more of #761317)
* Tue Dec  6 2011 Nalin Dahyabhai <nalin at redhat.com> 1.9.2-4

  consistently reset
* Tue Nov 22 2011 Nalin Dahyabhai <nalin at redhat.com> 1.9.2-2
- pull patch from trunk so that when computing an HMAC, we don't assume that
  the HMAC output size is the same as the input key length (RT#6994, #756139)
* Tue Nov 15 2011 Nalin Dahyabhai <nalin at redhat.com> 1.9.2-1

  things we were previously backporting, among other fixes
