It is in the /etc/sysconfig/nfs file, so it does not necessarily need to be in the /etc/init.d/nfs. It is supposed to handle authentication and you are having authentication problems, right?. I do not have your version of centos running but "SECURE_NFS" is not listed in /etc/init.d/nfs, it IS in /etc/rpcgssd and /etc/init.d/rpcvsgssd in centos 5.2, I'm betting that it is somewhat the same on your system. From Redhat documentation: https://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/en-US/Reference_Guide/s2-nfs-how-daemons.html "pc.svcgssd — This process is used by the NFS server to perform user authentication and is started only when SECURE_NFS=yes is set in the /etc/sysconfig/nfs file." "rpc.gssd — This process is used by the NFS server to perform user authentication and is started only when SECURE_NFS=yes is set in the /etc/sysconfig/nfs file." Notice that both of these talk about authentication, which is the problem you are having, right?
