Here are the reproduction steps:
I have 3 different servers hosting nfs client, server and KDC.
I set the ticket lifetime to 10 minutes on the client and server (in krb5.conf).
When adding a principal I used specified "-maxlife "10 minutes"
-maxrenew 2017-04-30".
I specified max_life (to 10 mins)
If I understand, you have renewable ticket and commands fail when the
ticket expires? I will let our folks tests it. Any more details on
reproducing this issue.

Has anyone seen client ops failing with error -13 because of context
expiry on client (gss_verify_mic fails).
Surprisingly with little load, it's consistently reproducible on my setup.
Can someone point me to the relevant commits if this has already been fixed.
Thanks,
Satya.

My bad, I should have mentioned the version in the original post.
Mahalal was kind enough to share a list of relevant commits. With the
patches I continued to see the issue. I suspect the client code is not
handling GSS_S_CONTEXT_EXPIRED correctly on a call to gss_verify_mic.
Instead I fixed the s

Actually, 2.4 has couple big features as far as ganesha project is
concerned, but Bill is probably indicating that libntirpc
corresponding to ganesha2.4 is mostly bug fix release.

Sorry, I should have asked long ago what version you were using.
On this list, I always assume th
We are using 2.3-stable. Given that most of our testing has been done
it's a bit difficult for us to move to 2.5 now but we can take fixes
from 2.5.
I put a similar fix (to the existing one in 2.5) but I am running into
another issue around the ticket renew time. Operations are failing on

removing recent cached entries resulting in permission errors. What
version are you using? Try using V2.5.

Looks mostly written by Matt, but Malahal made the most recent
changes in July 2016.

Is this a possibility :
Server first rejects a client op with CREDPROBLEM/REJECTEDCRED,
Client does an upcall and gssd initializes the context with the server.
However the server recycles it immediately before the operation was
retried (looks like there is a bug in the LRU implementation on

With libntirpc debugs enabled I could see all the three retries are
failing because of the unavailability of the creds in the cache. The
credentials are being removed by the reaper in the authgss_ctx_gc_idle
because of this condition -

Hi,
I am seeing "Permission denied" errors while running iozone on nfs
client with kerberos enabled. Digging further, I found there are a lot
of AUTH_REJECTEDCRED messages in nfs server log. NFS client tolerates
2 errors from server and tries to refresh the credentials. On the
third call it would
