Yes that is correct, it's my mistake, i was checking the correct links, i know the path is relative to /opt/kaltura/web, but this has been messing with my head...can't think straight.
[root@node1 0]# ls -al /opt/kaltura/web/content/generatedUiConf/23/448/ui_conf_23448682*
-rw-r-----. 1 apache kaltura 1747 Feb 2 2017 /opt/kaltura/web/content/generatedUiConf/23/448/ui_conf_23448682__12.config.xml

What look like beeing correct.
Also managed to create the test file
[root@node1 0]# nano /etc/passwd
[root@node1 0]# su - apache
-sh-4.1$ ^C
-sh-4.1$ touch /opt/kaltura/web/content/generatedUiConf/23/448/test
-sh-4.1$ ll /opt/kaltura/web/content/generatedUiConf/23/448/test
