Yes, all accessible to the Apache process. *But* please do see below
about the actual config.

MySQL.

No, I've been quite careful on that particular point.

Private mode all-around, no ad-blockers, nothing across a dozen clients.

Of course, here you go:

$ apache2 -v
Server version: Apache/2.2.22 (Ubuntu)
Server built:   Jul 12 2013 13:37:10

$ php -v
PHP 5.3.10-1ubuntu3.10 with Suhosin-Patch (cli) (built: Feb 28 2014
23:14:25)
Copyright (c) 1997-2012 The PHP Group

One thing I forgot to mention in my previous mail is that my setup is a
single Horde instance that serves multiple domains. The actual Horde
install is in /usr/share/php. I then have an Apache-readable
/var/www/horde that the mail/groupware parts of several sites use via fs
links.

Thanks again for any suggestions,

Cheers,
