The application server must use an approved DoW enterprise identity, credential, and access management (ICAM) solution to uniquely identify and authenticate users (or processes acting on behalf of organizational users).

To ensure accountability and prevent unauthorized access, application server users must be uniquely identified and authenticated. This is typically accomplished via the use of a user store, which is either local (OS-based) or centralized (LDAP). However, DoDI 8520.03 now requires that applications use an approved DoW enterprise (E-ICAM) solution whenever the ICAM solution addresses information system needs. Where the ICAM solution has been evaluated and found to not meet the needs of information system owners, information system owners must reevaluate decisions to use locally managed solutions and transition to DoW enterprise ICAM solutions to the maximum extent possible as the enterprise ICAM solutions mature.
