Permission error when "touch"ing file with different user
Hi,

There are 2 users (T886072 & T864764) that need to be provided full (rwx) access to a directory. I made the changes to the directory permissions using chmod and setfacl :

Code:
root@digidb2:[/root]# chmod 700 /u02/ftpfiles/MFRS16/discount_rates/
root@digidb2:[/root]# setfacl -s user::rwx,group::---,other:---,mask:rwx,user:T886072:rwx,user:T864764:rwx /u02/ftpfiles/MFRS16/discount_rates

This is how the directory permissions look after changes have been made :

Code:
root@digidb2:[/u02/ftpfiles/MFRS16/discount_rates]# ls -ld .
drwx------+  2 applprod other         96 Jan 18 11:21 .
root@digidb2:[/u02/ftpfiles/MFRS16/discount_rates]# getfacl .

# file: .
# owner: applprod
# group: other
user::rwx
user:T886072:rwx                #effective:rwx
user:T864764:rwx                #effective:rwx
group::---              #effective:---
mask:rwx
other:---
root@digidb2:[/u02/ftpfiles/MFRS16/discount_rates]#

With these permissions, the users are able to cd into the directory and touch files without problems. However, if I re-touch the same filename in the directory, I get the error below only for user T864764 .The other user (T886072) does not have this problem.

User T886072 :

Code:
bash-3.00$ id
uid=1331(T886072) gid=1(other)
bash-3.00$ pwd
/u02/ftpfiles/MFRS16/discount_rates
bash-3.00$ touch abc
bash-3.00$ ls -lrt
total 0
-rw-r--r--   1 T886072  other          0 Jan 18 14:34 abc
bash-3.00$ touch abc
bash-3.00$ ls -lrt
total 0
-rw-r--r--   1 T886072  other          0 Jan 18 14:34 abc
bash-3.00$ touch abc
bash-3.00$ ls -lrt
total 0
-rw-r--r--   1 T886072  other          0 Jan 18 14:35 abc
bash-3.00$ touch abc
bash-3.00$

User T864764 :

Code:
$ id
uid=1332(T864764) gid=1(other)
$ pwd
/u02/ftpfiles/MFRS16
$ bash
bash-3.00$ cd discount_rates/
bash-3.00$ pwd
/u02/ftpfiles/MFRS16/discount_rates
bash-3.00$ ls -lrt
total 0
-rw-r--r--   1 T886072  other          0 Jan 18 14:35 abc
bash-3.00$ touch abc
touch: cannot change times on abc: Permission denied
bash-3.00$ touch abc
touch: cannot change times on abc: Permission denied
bash-3.00$

Please help debug why this problem happens.
