Problem description: Have both NFS Server and NFS Client working on the same RedHat 6.0 ( rhel60sec02 ) with kernel version 2.3.32 running on the same box. The redhat server has the following installed: Installed: nfs-utils.x86_64 1:1.2.2-7.el6 nfs4-acl-tools.x86_64 0:0.3.3-5.el6 rpcbind.x86_64 0:0.2.0-8.el6 Dependency Installed: libevent.x86_64 0:1.4.13-1.el6 libgssglue.x86_64 0:0.1-8.1.el6 libtirpc.x86_64 0:0.2.1-1.el6 nfs-utils-lib.x86_64 0:1.1.5-1.el6 Machine is joined to the domain and it is defined in DNS as rhel60sec02.ngdclab.local Shared directory: /var/share Mount point: /mnt Windows is 2008 R2 server with 2008 Domain level. Followed the instructions from Tom's blog in addition with KB article and set up exports, fstab on the same box. The upn is set on rhel60sec02 server in AD to 'nfs/rhel60sec02.ngdclab.local@NGDCLAB.LOCAL'. As root, running kinit -k rhel60sec02$ gets the ticket with RC4 enc type. So NFS Client is working but when we run the command : mount -t nfs4 -o sec=krb5 rhel60sec02:/ /var/mnt results in Access denied generic error message. Turned on verbose level logging on both rpc.gssd and rpc.svcgssd which brings up the following error messages: Nov 4 13:01:27 rhel60sec02 rpc.gssd[10897]: WARNING: Failed to create krb5 context for user with uid 0 for server rhel60sec02.ngdclab.local Nov 4 13:01:27 rhel60sec02 rpc.svcgssd[10943]: finished handling null request Nov 4 13:01:27 rhel60sec02 rpc.svcgssd[10943]: entering poll Nov 4 13:01:27 rhel60sec02 rpc.gssd[10897]: WARNING: Failed to create machine krb5 context with credentials cache FILE:/tmp/krb5cc_machine_NGDCLAB.LOCAL for server rhel60sec02.ngdclab.local Nov 4 13:01:27 rhel60sec02 rpc.gssd[10897]: WARNING: Failed to create machine krb5 context with any credentials cache for server rhel60sec02.ngdclab.local Nov 4 13:01:27 rhel60sec02 rpc.gssd[10897]: doing error downcall Nov 4 13:01:27 rhel60sec02 rpc.gssd[10897]: destroying client /var/lib/nfs/rpc_pipefs/nfs/clnt55 Nov 4 13:01:27 rhel60sec02 rpc.gssd[10897]: destroying client /var/lib/nfs/rpc_pipefs/nfs/clnt54 No matter what we do, we are unable to get past the above error. Appreciate any help.
