Yes, its been supported since 3.1:
https://www.ja-sig.org/svn/cas3/trunk/cas-server-core/src/main/java/org/jasig/cas/authentication/DirectMappingAuthenticationManagerImpl.java

It essentially accepts a map of "credentialsMapping" where the key is the
Credentials class and the value is a
DirectAuthenticationHandlerMappingHolder (which takes an authentication
handler and a credentialstoprincipalresolver).

Cheers,
Scott
