2.5.3.2 Multiple Domains

The following subsection describes a use case that pertains to interactive domain logon in a cross-domain environment. For example, a user account is provisioned in one domain (domain1), a client computer is joined to another domain (domain2), and both domains are in the same forest. A user attempts to log on interactively to a machine that is joined to domain2. In this use case, AA1 denotes the Authentication Authority (AA) of domain1, AA2 denotes the AA of domain2, and Account DB #1 and Account DB #2 denote the account databases for domain1 and domain2, respectively. For a similar example, see section 2.5.4.2 and use case diagram section 2.5.4.2.1.
