We have several developers who maintain the system and I want them to easily read the log files in /var/log/httpd without needing root access. I set the read permission for 'other' users but when I run tail on the log files I get permission denied:

[root@ourserver httpd]# chmod -R go+r /var/log/httpd
[root@ourserver httpd]# ls -la
drwxr--r--  13 root root 4096 Oct 25 03:31 .
drwxr-xr-x.  6 root root 4096 Oct 20 03:24 ..
drwxr-xr-x   2 root root 4096 Oct 20 03:24 oursite.com
drwxr-xr-x   2 root root 4096 Oct 20 03:24 oursite2.com
-rw-r--r--   1 root root    0 May  7 03:46 access_log
-rw-r--r--   1 root root 3446 Oct 24 22:05 error_log

[me@ourserver ~]$ tail -f /var/log/httpd/oursite.com/error.log
tail: cannot open `/var/log/httpd/oursite/error.log' for reading: Permission denied

Maybe I'm missing something on how permissions work but I'm not finding any easy answers on it.
