The XMPP module implements the XEP-0114 extension (Jabber Component Protocol). It allows "trusted components" to connect to the CommuniGate Pro XMPP module. Usually these "trusted components" are external servers acting as gateways to some other IM/Presence networks.
Use the WebAdmin Interface to open the Receiving page in of the XMPP Module Settings.
Component Password: Use this field to set a password ("shared secret") string. When "trusted components" connect to the XMPP module, they must present this password in order to establish a connection.
The "trusted components" specify the domain name they are serving. The XMPP Module accepts all Signal addresses routed to any domain specified by any "trusted component" and it relays these Signals to the "trusted component" via the extablished XMPP connection. If, for example, a "trsuted component" has connected to the XMPP Module to serve the icq.company.dom domain, then all Signal requests directed to any address in the icq.company.dom domain is accepted with the XMPP module, and it delivers the Signal request to this "trusted component" (which is likely to be a gateway to the ICQ network).
