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 ! alex > > > > -- > "There's no such thing as legacies. At least, there is a legacy, but I'll never see it." > > - George W.
