ACL is set with 'setfacl' but does not work as expected

Issue

• ACL is set but it does not work as it is configured
• See an example below:

[splunk@SKT-DMHPAP2 log]$ getfacl secure
# file: secure
# owner: root
# group: root
user::rw-
user:splunk:r--
group::---
mask::r--
other::---


[splunk@SKT-DMHPAP2 log]$ ls -al secure
-rw-r-----+ 1 root root 603161 Oct 23 10:06 secure

splunk@SKT-DMHPAP2 log]$ getfacl /var/log
getfacl: Removing leading '/' from absolute path names
# file: var/log
# owner: root
# group: root
user::rwx
group::r-x
other::r-x

[splunk@SKT-DMHPAP2 log]$ cat secure |grep "Oct 23"
cat: secure: Permission denied       <===========================

• user or group cannot access files or directories when ACL are set to allow them.
