!!! Overview
[{$pagename}] is an [XDASv2 Event] involving the association of a user or identity with a group, or the association of two users in some domain-specific context. 

For example, adding an LDAP user to a group, or associating two users for a domain-specific purpose in an application's identity association database. [{$pagename}] events are also related to the association of identities within disparate authentication domains for purposes of federation.

For example, when an identity in domain A makes a request to a service governed by domain B, then a peer association is required between these domains – often this is called a trust relationship. 

From an implementation perspective, setting up a trust relationship is often done by establishing an identity in domain B, which is used as a proxy for any request coming from any identity in domain A. Trust relationships can be much more complex, however, as individual identities in domain A can have individual associations with specific domain B identities.
