I have a client that is looking to migrate to Exchange 365 and are interested in migrating other services to the 365 platform (onedrive/fileaccess/team sites). I am looking for the simplest way to implement SSO within the environment to allow for access across the board, initially between 365, local AD and Sales force. I know that i could implement ADFS or go for a 3rd party solution. At present implementing ADFS would me creating an additional set of servers for Proxy and authentication and so this seems to defeat the object of moving to cloud services (remove 1 server but add 2).
Is there a way to link the local AD to the Azure Active directory as it seems there is good integration from the Azure SSO to 3rd party apps out there:
Has anyone completed this before and/or could you point me in the right direction?
