[TYPO3] clearCacheCmd backend user rights?

[Peter Gyongyosi]

Hi all,

I'm having the following problem that I cannot really solve:

I have a mainly news-oriented Typo3 4.0 site using the latest tt_news 
plugin. As most of its parts contain news at some point, I have 
TCEMAIN.clearCacheCmd = all set in the TSconfig of the news storage 
page. It works fine when any change is made logged in as an admin user, 
the cache gets expired and renewed at the next page hit. But when any 
change is made logged in as a news or site admin user (both are 
non-admin backend users, the former having access only to the news 
storage page and news-type pagecontent, the latter to all pages and the 
basic pagecontent elements), the cache is not refreshed at all. If the 
page is viewed logged in with any backend user, the changes do show up, 
but the cache_pages table is still unmodified until a manual "clear FE 
cache" is pressed or the news storage page is edited by an admin or the 
daily automatic cache expiration needed by other modules happens.

Does clearCacheCmd require any special rights for the backend user 
making the changes to show its effect? Or what else should I check?

Any ideas are welcome.

Thanks,
Peter
