[horde] Server Error

[The Web Center, Inc.]

I have installed the current versions of Horde and IMP here for
experimentation:

http://vs03.tvsecure.com/~vs03000/horde/test.php

However, any attempt to access the scripts using this domain, or even to
access test.php with a specific domain. produces a permission error:

http://vs03.tvsecure.net/horde/test.php
http://linuxadministration.com/horde/test.php
http://vs03.tvsecure.com/~vs03000/horde/imp/

I am working with the sysadmins on this, but I am also hoping someone else
has run into the same situation and has a few pointers...?

Thanx,

Darrell
