Problem exporting NFS filesysytem with root permissions to Linux

Hi,

I have a Solaris 10 server and I want to export a filesystem to a linux client and give the client's root user root priviliges on the filesystem.
The client is an ubuntu 14.04 LTS server.
the dfstab on the server looks lik this:
Code:
 /usr/sbin/share -F      nfs     -o      sec=sys,rw,root=something.somewhere.nl:@192.168.1.0 -d "user home dirs"    /home/t4   -

The linux server is on the 192.168. network. The fstab line looks like:
Code:
tmku201:/home/t4    /home/tmku201    nfs    defaults    0    0

The mounting works perfectly, but root of the Linux server can not delete files on /home/tmku201.

Do you have any ideas?
Regards,
Nico

Replying to my own post I think I fixed it.
I changed the fstab line on the Linux server:

Code:
192.168.1.101:/home/t4    /home/tmku201    nfs    defaults    0    0

You know, my servers have the first network interface attached to the university network and the second to the 192.168. backend.

And in the first fstab I mixed things up a bit. tmku201 is the hostname on the university network for the Solaris server and I want to mount over the backend.
Strange though that the mount succeeded at all

Rregards,
Nico

NAME
bsmconv, bsmunconv - enable or disable the Basic Security Module (BSM) on Solaris SYNOPSIS
/etc/security/bsmconv [rootdir...] /etc/security/bsmunconv [rootdir...] DESCRIPTION
The bsmconv and bsmunconv scripts are used to enable or disable the BSM features on a Solaris system. The optional argument rootdir is a list of one or more root directories of diskless clients that have already been configured. See smdiskless(1M). To enable or disable BSM on a diskless client, a server, or a stand-alone system, logon as super-user to the system being converted and use the bsmconv or bsmunconv commands without any options. To enable or disable BSM on a diskless client from that client's server, logon to the server as super-user and use bsmconv, specifying the root directory of each diskless client you wish to affect. For example, the command: myhost# bsmconv /export/root/client1 /export/root/client2 enables BSM on the two machines named client1 and client2. While the command: myhost# bsmconv enables BSM only on the machine called myhost. It is no longer necessary to enable BSM on both the server and its diskless clients. After running bsmconv the system can be configured by editing the files in /etc/security. Each diskless client has its own copy of configu- ration files in its root directory. You might want to edit these files before rebooting each client. Following the completion of either script, the affected system(s) should be rebooted to allow the auditing subsystem to come up properly initialized. FILES
The following files are created by bsmconv: /etc/security/device_maps Administrative file defining the mapping of device special files to allocatable device names. /etc/security/device_allocate Administrative file defining parameters for device allocation. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsr | +-----------------------------+-----------------------------+ SEE ALSO
