I am using Red Hat for NFS with Kerberos client:

[root@perf-c238 ~]# cat /proc/version 
Linux version 2.6.18-92.el5 (brewbuilder@ls20-bc2-13.build.redhat.com) (gcc version 4.1.2 20071124 (Red Hat 4.1.2-41)) #1 SMP Tue Apr 29 13:16:15 EDT 2008

NFS with Kerberos server is :

[root@krbserver ~]# cat /proc/version 
Linux version 3.9.6-200.fc18.i686 (mockbuild@bkernel01.phx2.fedoraproject.org) (gcc version 4.7.2 20121109 (Red Hat 4.7.2-8) (GCC) ) #1 SMP Thu Jun 13 19:29:40 UTC 2013

While doing mount, I am getting "Permission denied" error, and am seeing these messages in /var/log/messages on the client:

Apr  6 09:03:03 perf-c238 rpc.gssd[29050]: WARNING: Failed to obtain machine credentials for connection to server krbserver.test.com

Can someone please help in debugging this?

Thanks!

Your kerberos setup on the would appear to be incorrect. (unless you edited your output to say krbserver.test.com)

https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/5/html/Configuring_Identity_Management/nfs.html

If kinit does not work also, look in /var/log/krb5.log. Make sure /etc/krb5.conf is set up to reflect your setup.
