A system, method, and computer program product are provided to facilitate changing authentication information in an environment having two or more configuration items. Establishing a connection between the configuration items may require matching authentication information corresponding to the first configuration item with authentication information transmitted from the second configuration item. The system may include a repository storing at least one predetermined attribute corresponding to a configuration item, and a relation between the configuration item and another configuration item. The attribute and/or the relation may be updated by discovery that detects information regarding configuration items. In response to a request to change authentication information corresponding to the first configuration item, and based on the relation, an identification unit may identify a second configuration item influenced by the change. An instruction unit may initiate a change of authentication information transmitted from the second configuration item.
