mod_vhost_ldap is an Apache 2.x module for storing and configuring 
virtual hosts from LDAP. It supports DocumentRoot, ScriptAlias, 
ServerName, ServerAlias, ServerAdmin, and SuexecUserGroup directives. 
It's built on top of mod_ldap, so it uses its caching capabilities and 
can be used with a threaded Apache httpd.
