Instead, show us the mount command used or the according (if applicable) /etc/fstab line.
I've tried about 50 combinations, in the current and most simple form I use /etc/fstab

Code:
#
# Warning - this file should only be modified with vifs(8)
#
# Failure to do so is unsupported and may be destructive.
#
cady:/volume1/nfs       /System/Volumes/Data/nfs        nfs     rw

But in an attempt to try a lot of different combinations quickly I just used mount commands directly. Here's a sampling from my history.

Code:
mount cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o resvport cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o noacl cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o nolock cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o nfsvers=4 cady:/volume1/nfs /System/Volumes/Data/nfs
mount_nfs -o nfsvers=2 cady:/volume1/nfs /System/Volumes/Data/nfs
mount -o rw,sync,no_root_squash,no_subtree_check,insecure cady:/volume1/nfs /System/Volumes/Data/nfs
...
...

Using either mount commands directly, or using auto_master/auto_nfs, or /etc/fstab I can easily get the NFS drive mounted, and the permissions and ownership is correct. From a shell I can copy files to/from the local system to the NFS mount without troubles. The logs on the NFS server show no errors. I've already posted the unhelpful error log from the client machine.

I've tried lots of different combinations of owner/group/permissions via chown, chgrp and chown. Currently sitting at:

Code:
brians-mbp:etc root# ls -la /System/Volumes/Data/nfs/hosts
-rwxrwxrwx 1 1024 _lpoperator 2393 Feb 8 14:29 /System/Volumes/Data/nfs/hosts

I was hoping somebody familiar with how Mac OS X specifically creates the environment in which Launchd or cron jobs run could shed some light. Even though root has access to the files, and the Launchd or cron job is owned by root, it somehow isn't executed with normal root rights.

nfsmapid

nfsmapid(1M)						  System Administration Commands					      nfsmapid(1M)

NAME

       nfsmapid - NFS user and group id mapping daemon

SYNOPSIS

       /usr/lib/nfs/nfsmapid

DESCRIPTION

       The  nfsmapid  daemon  maps to and from NFS version 4 owner and owner_group identification attributes and local UID and GID numbers used by
       both the NFS version 4 client and server.

       nfsmapid uses the passwd and group entries in the /etc/nsswitch.conf file to direct how it performs the mappings.

       The nfsmapid daemon has no external, customer-accessible interfaces. You can, however, administratively configure nfsmapid in  one  of  the
       following ways:

	   o	  Specify the NFSMAPID_DOMAIN parameter in nfs(4)

	   o	  Specify the _nfsv4idmapdomain DNS resource record.

       Please refer to the  for further details.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       +-----------------------------+-----------------------------+
       |Availability		     |SUNWnfscu 		   |
       +-----------------------------+-----------------------------+

SEE ALSO

       svcs(1),  automountd(1M),  groupdel(1M),  groupmod(1M),	mount_nfs(1M),	passmgmt(1M), svcadm(1M), share_nfs(1M), userdel(1M), usermod(1M),
       nfs(4), attributes(5), smf(5)

NOTES

       The nfsmapid service is managed by the service management facility, smf(5), under the service identifier:

	 svc:/network/nfs/mapid

       Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed  using  svcadm(1M).  The  ser-
       vice's status can be queried using the svcs(1) command.

       If  it is disabled, it will be enabled by mount_nfs(1M), share_nfs(1M), and automountd(1M), unless  its	     application/auto_enable prop-
       erty is set to false.

       nfsmapid caches a user's UID and GID. If a user subsequently changes a UID or GID, using one of the utilities listed  below,  the  nfsmapid
       cache becomes stale. At this point, any NFS operation that gets or set attributes will result in the exchange of this stale information. To
       resolve this situation, restart nfsmapid, as follows:

	 # svcadm restart svc:/network/nfs/mapid:default

       The utilities that allow you to change UID and GID are:

	   o	  usermod(1M)

	   o	  userdel(1M)

	   o	  groupmod(1M)

	   o	  groupdel(1M)

	   o	  passmgmt(1M)

       The nfsmapid daemon might not exist in a future release of Solaris.
