Thank you Bob.Bob, if you can help with another question which i already posted in a separate thread. Its urgent actually we are doing a POC to make call from DPS cloud to AEM author instance by writing a javascript call but we are getting cross domain error "Access-Control-Allow-Origin".Really appreciate your help.How can i make call to AEM author instance from DPS 2015

Thank you Lars that is very good explanation. Let me work on that.Thanks,Vamshi

Thank you Lars for quick reply. Really appreciate.If we already have an existing authentication server can we configure with DPS?Lets say there is xyz website (which is in AEM ) where they want to make use of DPS 2015 for publishing their content at the same time they want to authenticate using their LDAP/ID server and then show the content based on the role. Is this achievable if yes could you please know if it is code level change or configuration?Thank you so much for your help.Thanks,Vamshi
