Returns if we want components to be able to connect multiple times to the
same JID. This is a custom Openfire extension and will not work with any
other XMPP server. Other XMPP servers should ignore this extra setting.

@param subdomain
the sub-domain.
@return True or false if we are allowing multiple connections.
