Just to add some more information to this (i typed this up late last
night)
I have 3 servers and 1 laptop. I am using ldap for my userid / password
info. I am using libnss-ldapd (fork of libnss-ldap)
I have a user alex who is a member of group movies
on the nas server
I have a directory
/exports/video/tmp
drwxrwsr-x 2 video movies 20 2008-06-27 07:23 tmp
if I go to this directory and try touch HEREIAM, a file is created
now when I go to machine multimedia, which has nas:/exports/video mount
as /exports/video and I try the same thing it works
when I go to my laptop, which has the same mounts and try the same thing
I get permission denied. And the same error when i try it from the
other server hufpuf.
I did a tcp dump on the nas box watch everything except for port 22 and
ran the same tests on all the machine a NFS ok reply is sent back after
the create request !
I ran another test on the machines that gave me access denied, I went to
a local partition and created a directory with the same permissions as
/exports/video/tmp and tried to create a file in the same manor - it
worked on all the servers
I have also looked at the mount command options (fstab) and they are the
same. I have tried reboot the machines
I don't have selinux turned on
I have looked at package versions of
libc
libnss-ldapd
mount
linux-image
I have tried stracing this command "touch d", but all I can see is a
open request and a fail or ok on the respective servers.
I am at a bit of a loss where to look now :(
help !
