The IdentityTrustManager interface can use the information in a security context to make a trust-based decision. The possible outcomes of a trust-based decision are:
  • PERMIT — the framework trusts the identity completely, and bypasses authentication
  • DENY — access is denied. This outcome acts as a virtual firewall.
  • NOTAPPLICABLE — the framework cannot process the security context provided, and the process must be passed further (to the authentication phase).
Implementations can use IdentityTrustModules to make trust-based decisions.
