Could not find artifact name for pom . Need to implements Delegated Authentication Directory

Hi all,
can anybody give me artifact which I should to place in pom to have acces to the
com.atlassian.crowd.directory.DelegatedAuthenticationDirectory

Standard crowd-api
gives access to the RemoteDirectory but I need DelegatedAuthenticationDirectory
& can’t find it …

This is crowd-integration-client-api
But, have a bit deeper question - above artifact doesn’t provide other models like
com.atlassian.crowd.integration.model.RemoteGroup

Can I found anywhere mapping artifacts per classes or something like this ?
I reviewed all crowd integration artifacts but doesn’t find
com.atlassian.crowd.integration.model.RemoteGroup …
