UniquePrincipalAuthenticationPolicy (cas-server-core-authentication-api 6.0.0-RC2 API)

java.lang.Object
- org.apereo.cas.authentication.policy.UniquePrincipalAuthenticationPolicy

All Implemented Interfaces:

org.apereo.cas.authentication.AuthenticationPolicy, org.springframework.core.Ordered
```
public class UniquePrincipalAuthenticationPolicy
extends java.lang.Object
implements org.apereo.cas.authentication.AuthenticationPolicy
```
This is UniquePrincipalAuthenticationPolicy that prevents authentication if the same principal id is found more than one in the registry. This effectively forces each user to have a single and unique SSO session, disallowing multiple logins.
