Configuring ACL on AIX 5.3
Hello All,

Let me quickly come down to my problem..

I have a file with following description:

==
root:/me01/tia/filetr ans # ls -lrt DW_NUM_OF_ROWS_TSP.txt
-rwxrwxr-- 1 tiaoas oinstall 43 Jun 07 17:12 DW_NUM_OF_ROWS_TSP.txt
root:/me01/tia/filetrans # aclget DW_NUM_OF_ROWS_TSP.txt
*
* ACL_type AIXC
*
attributes:
base permissions
owner(tiaoas): rwx
group(oinstall): rwx
others: rwx
extended permissions
enabled
permit rw- u:tiaadm,g: oinstall
==

I wanted user 'tiaadm:staff' to be able to do a 'chmod 777 DW_NUM_OF_ROWS_TSP.txt' -- for which I permitted this user for 'rw' as shown in the 'aclget' o/p above. However, my purpose was that any file which begins with 'DW', user 'tiaadm:staff' should be able to do a 'chmod', hence setting ACL for individual files wasn't quite a right option.
Google'ng around, someone suggested to set the ACL for the parent directory under which files starting with 'DW' exists, so this is what I did:

==
aclget DW_NUM_OF_ROWS_TSP.txt | aclput -R /me01/tia/filetrans
==

With this, my purpose wasn't solved as new files(getting created) starting with 'DW' under ~/filetrans directory didn't allow user 'tiaadm:staff' to do a 'chmod 777'.
Later, some online forum suggested to use "Extended Attribute Format" for inheritance under directories, so this is what I did:

==
root:/ # chfs -a ea=v2 /me01

root:/me01/tia # aclconvert -t NFS4 filetrans

root:/me01/tia # aclget filetrans
*
* ACL_type NFS4
*
*
* Owner: tiaesg
* Group: oinstall
*
s: (OWNER@): a rwpRWxDaAdcCs
s: (OWNER@): d o
s: (GROUP@): a rwpRWxDadcs
s: (GROUP@): d Co
s: (EVERYONE@): a rwpRWxDadcs
s: (EVERYONE@): d Co
u:tiaadm: a rwpxo fidi
g: oinstall: a rwpxo fidi
==

Even with the above options implemented, this is what I see:

==
tiaadm:/me01/tia/scripts% chmod 777 /me01/tia/filetrans/DW*
chmod: /me01/tia/filetrans//DW_NUM_OF_ROWS_TSP.txt: Operation not permitted.
==

I find myself absolutely lost & messed up here. Could someone kindly suggest/help getting this sorted?


Cheers,
Souvik
