Comment 1 David Woodhouse 2016-01-05 17:34:07 UTC
Addressed by https://github.com/krb5/krb5/pull/385

Comment 2 David Woodhouse 2016-01-05 17:35:03 UTC
Seen in F22 too

Comment 3 Robbie Harwood 2016-01-06 13:38:26 UTC
I'll backport the fix from upstream once Simo's PR has merged.

Comment 4 David Woodhouse 2016-01-08 16:56:10 UTC
It's merged now: https://github.com/krb5/krb5/commit/3beb564cea3

Scratch build for F23 at
http://koji.fedoraproject.org/koji/taskinfo?taskID=12468174

I don't seem to be able to build for F22 though; the build fails (in an apparently unrelated way). When it fails, the failure in 
http://koji.fedoraproject.org/koji/taskinfo?taskID=12468199 should look something like:

Comment 5 Robbie Harwood 2016-01-08 18:59:37 UTC
Yeah, as per comments on IRC that's due to a bug in nss_wrapper.  I've fixed it before in f23 and rawhide, so I guess f22 will get the fix too with this update.

Anyway, packages are building; expect a bodhi update in an hour or so.
