Horde supports multiple tenants.
You can even modify the registry to show a different menu structure for 
individual hosts.

The vhosts feature can be turned on in horde/config/conf.php

config will be the merge of conf.php and conf-$vhost.php

Registry will process in this order:

registry.php (do not edit this file)
registry.d/*.php (for snippets)
registry-$vhost.php
registry.local.php

The latter will overwrite the former.
Having a vhost specific conf.php will impair usability of the config UI 
as the config will be populated with the vhost specific content. Do not 
copy/paste conf.php to vhost config but only copy&adapt the vhost 
specific items.

Generally, your .local or -$vhost files should only contain explicitly 
changed entries.
