[Kolab-devel] permission problem with caching feature

The cache files probably originate from Horde template
processing. Take a look at their contents to be certain. It is
definitely strange that these files are owned by root because they
should have been written by the web server. Maybe they are old files?

On what occasions does Horde display these messages? I assume that you
only see the messages after performing specific actions. Or does it
occur randomly?

In any case the problematic files should NOT originate from the new
caching of Kolab groupware objects. These are named "kolab_cache*".

Just as a side note though I guess you know that: you will need to
apply some of the patches from current Kolab CVS in order to get the
full compatibility.

Cheers,

Gunnar
