Are Crowd (or somerhing else) included in the OnDemand concept? I cant see that you can choose crowd in the OnDemand site.
I guess its inbuilt.
Ondemand automatically comes with crowd. This is indeed used to create a SSO environment for the OnDemand instance.
Currently it is (not yet) possible to connect to an external Crowd server. We have an improvement case open for this [here|https://studio.atlassian.com/browse/JST-3397]
