Unlike many of the plugin types supported by the SP, there is no specific XML element that is normally used to load an EntityMatcher. Rather, other plugin types rely on this mechanism and include the configuration content identified below based on the type of EntityMatcher plugin used. There is typically, but not always, a matcher attribute used to specify the type of plugin.

Table of Contents


Name EntityMatcher

Matches an IdP based on its entityID or the name of an enclosing <md:EntitiesDescriptor> element in its metadata, informally referred to as a "group" name.
