Comment 1 nneul 2014-04-17 17:51:27 UTC
selinux is disabled on the box.

Comment 2 Balint Cristian 2014-04-30 13:53:08 UTC
* krb5-workstation-1.11.3-33.fc20.x86_64 seems to work fine.

- Can try downgrade and confirm ?

Comment 3 nneul 2014-04-30 14:00:06 UTC
Confirmed. 1.11.3-33 does not exhibit the symptom.

Comment 4 nneul 2014-04-30 14:07:50 UTC
1.11.3-39 also works. Will try to narrow down for you.

Comment 5 nneul 2014-04-30 14:11:24 UTC
1.11.5-2 broke
1.11.5-4 broke
1.11.5-5 broke

It's got to be this change:

* Fri Jan 31 2014 Nalin Dahyabhai <nalin> - 1.11.3-40
- add currently-proposed changes to teach ksu about credential cache
  collections and the default_ccache_name setting (#1015559,#1026099)

Comment 6 nneul 2014-05-27 21:26:35 UTC
Any news on this bug? It pretty much renders ksu non-functional.

Comment 7 Nalin Dahyabhai 2014-05-27 21:57:55 UTC
I'm planning on digging into this while making revisions per feedback in the upstream pull request; unfortunately there are a few items in other packages which are ahead of it on my schedule.

In the meantime I'm building krb5-1.11.5-6.fc20 with those changes backed out, which will at least works for FILE: caches.  Sorry for the disruption.

Comment 8 nneul 2014-05-28 12:16:37 UTC
Appreciate it. Thank you!

Comment 9 Fedora Admin XMLRPC Client 2014-10-06 16:38:04 UTC

Comment 10 Fedora End Of Life 2015-05-29 11:36:22 UTC
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Comment 11 Fedora End Of Life 2015-06-29 20:09:46 UTC
Fedora 20 changed to end-of-life (EOL) status on 2015-06-23. Fedora 20 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
