Legacy Authentication

Legacy authentication components are enabled by including the following dependencies in the Maven WAR overlay:

<dependency>
         <groupId>org.jasig.cas</groupId>
         <artifactId>cas-server-support-legacy</artifactId>
         <version>${cas.version}</version>
    </dependency>

Legacy Components

CAS provides the following components to accommodate different legacy authentication needs for backwards compatibility:

LegacyAuthenticationHandlerAdapter

Adapts a CAS 3.x AuthenticationHandler onto a CAS 4.x AuthenticationHandler. If the supplied legacy authentication handler supports NamedAuthenticationHandler, then its defined name will be used to identify the handler. Otherwise, the name of the class itself will be used.

CredentialsAdapter

Interface to be implemented by adapters to determine how credentials need be converted over to CAS 4.

UsernamePasswordCredentialsAdapter

Adapts and converts a CAS 4 username/password credential into a CAS 3.x username/password credential.

Sample Configuration

<bean id="legacyAuthHandler"
      class="org.jasig.cas.authentication.LegacyAuthenticationHandlerAdapter"
      c:legacy-ref="cas3LegacyAuthenticationHandler"
      c:adapter-ref="usernamePasswordCredentialsAdapter" />
