nfs or acl?

[Michael Weiner]

Dear list readers -

Having an interesting problem that i cannot seem to find a good answer for,
so i thought i would throw it out to the list and maybe learn something in
the process. I have an unusual issue on an auto-mounted over NFS data
directory. The users are complaining that they get permission problems when
copying files in their own directories, and when i took a look from one of
the workstations that had the data directory mounted, at first things
appeared ok, i saw what i would expect to see, example:

drwxr-sr-x   2 yangj2 qinlab     98 Jun  2 20:08 PDB_files
-rw-r--r--   1 yangj2 qinlab   4567 Jan 18  2008 prompt.txt
drwxr-sr-x   2 yangj2 qinlab      6 Apr 10  2007 .qt
-rw-r--r--   1 yangj2 qinlab 111789 Aug 13 12:21 Restraints.py.pdf
drwxr-sr-x  18 yangj2 qinlab     18 Oct 16 11:43 Scripts
drwxr-sr-x   7 yangj2 qinlab      7 Aug  4  2006 Setup_Files
drwxr-sr-x   8 yangj2 qinlab     34 Aug 21 13:13 Test
drwx--S---   3 yangj2 qinlab      3 Apr  3  2007 .thumbnails
drwxr-sr-x   2 yangj2 qinlab      2 Oct 31 16:39 Transfer
-rw-r--r--   1 yangj2 qinlab      2 May 10  2005 update_20060201
-rw-------   1 yangj2 qinlab   5703 Apr 10  2007 .viminfo
-rw-------   1 yangj2 qinlab    160 Apr 10  2007 .Xauthority

*note: that is from a fedora core 2 machine*.

But when i took a look from another one of their machines mounting the exact
same share, i see the following:

drwxr-sr-x+  2 yangj2 qinlab     98 2008-06-02 20:08 PDB_files
-rw-r--r--+  1 yangj2 qinlab   4567 2008-01-18 15:59 prompt.txt
drwxr-sr-x+  2 yangj2 qinlab      6 2007-04-10 13:50 .qt
-rw-r--r--+  1 yangj2 qinlab 111789 2008-08-13 12:21 Restraints.py.pdf
drwxr-sr-x+ 18 yangj2 qinlab     18 2008-10-16 11:43 Scripts
drwxr-sr-x+  7 yangj2 qinlab      7 2006-08-04 15:49 Setup_Files
drwxr-sr-x+  8 yangj2 qinlab     34 2008-08-21 13:13 Test
drwx--S---+  3 yangj2 qinlab      3 2007-04-03 16:56 .thumbnails
drwxr-sr-x+  2 yangj2 qinlab      2 2008-10-31 16:39 Transfer
-rw-r--r--+  1 yangj2 qinlab      2 2005-05-10 15:20 update_20060201
-rw-------+  1 yangj2 qinlab   5703 2007-04-10 14:38 .viminfo
-rw-------+  1 yangj2 qinlab    160 2007-04-10 14:56 .Xauthority

*note: that is from a fedora 7 machine.*

The mount is auto-mounted over nfs from a Solaris 10 x86 running ZFS. What
is puzzling me is the '+' character in the permissions, which i am honestly
unfamiliar with. After a little digging i believe this is indicative of some
extended ACL that is applied somewhere but i cant seem to determine where.
Its not the older FC boxes, i dont THINK its the solaris box, and i am
hedging a bet its the F7 boxes, but not sure at this point exactly what it
is. Is it NFSv4, or something else? And how can i remove that set bit from
the files and directories. Not sure if thats really the problem, but on
systems that i DONT see that '+' we dont have the problem.

Any direction or ideas would be greatly appreciated.

Thanks in advance
Michael Weiner
