I have a customer scenario which is a group company with multiple companies within it. Here are the different questions that I am supposed to answer them.
- They have multiple entities each having their own O365 tenant
- Each of them their own On-Premise AD and have their AD-FS Configured, so users are able to login through their AD Usernames to their O365 Subscription
- Now they want to setup up a Central Workspace (assume it is setup as a new O365 – SharePoint Online tenant) – which all of these companies can post and share data with, there is a Group Head Office, which controls this and they have their own AD as well
- In this central workspace, there will be documents shared, tasks created, discussion forums, surveys, social features etc.
- They do not want to do any AD Consolidation – so they are asking me – how will the authentication work in the future – each of the group company users should be able to login with their AD Username itself
- Is this possible? If so, How can we do this?
- Also with respect to Performance, it will be around 2000 users using this central workspace – so will O365 – SharePoint Online automatically scale or is there any special configuration that needs to be done?
- In the future, they are looking at extending this to 3<sup>rd</sup> party companies as well to share information with – so there is a question as to how they can get authenticated as well (External Sharing is not really their preference) so is there like an FBA – Claims (Custom Login Page) we can setup along with Self-Registration capabilities?
- Again, when around 10000 users use this later, how will O365 – SharePoint Online perform?
- In the future, how will Yammer and the new Office Groups work? Will Yammer go away? What is the direction that Microsoft is taking?
Would be great to get your responses at the earliest possible.
