Hi Brad,
thanks for your quick reply!
No, we don't want to use the services to authenticate users.We did see the authentication providers possibilities - which is quite helpful.
We want to have the users in Crowd (working as an SSO-Provider) and/or Jive (not sure how this works out). Additionally we need to check from an external system (cms) if a user is already registered with a certain email-address. Therefore Clearspace/SBS offers an according REST service which works well if the users are in Jives database. I don't know how this behaves if the user data is (also?) in Crowd.
Thank you & Regards -- Tobias
