SOA systems identify infrastructural services that are needed by other services to achieve a complete functional architecture. In many cases, certain functions cut across many others. These "cross cutting concerns" provide a challenge to the organization to come up with ways to manage them in a more holistic way.
The article suggests that applications of this this technology can include companies exposing their applications to external trading partners, compliance with government regulations such as Sarbanes-Oxley, and the integration of merged companies. It quotes the wikipedia, which defines Identity Management as:
"Identity Management (IM) is an integrated system of business processes, policies, and technologies that enable organizations to facilitate and control their users' access to critical online applications and resources - while protecting confidential personal and business information from unauthorized users. It represents a category of interrelated solutions that are employed to administer user authentication, access rights, access restrictions, account profiles, passwords, and other attributes supportive of users' roles/profiles on one or more applications or systems."
The article goes on to suggest the connection between identity and selective policy enforcement.
