Office 365 migration with different AD but same domain for email and other considerations
Hi folks, I have the following scenario and I'd love to hear your feedback. - The organization has two entities, let's say A and B - Two domains. Entity A has @abc.com and entity B had @cde.c...
- AD connect recommended topology, how should we sync users? Should we use email as UPN? (SSO would not work because it requires different domains to distinguish users from A and B)
SSO will not work regardless as UPN's need to be existing and authenticated in a single domain
- If we add the two domains, abc.com and cde.com, can a B user login with their AD credentials B@cde.com but have a different email address B@abc.com. There would be only a hybrid exchange server which is managed by A entity. What configuration could work?
Yes that is fine as you just add both domains to AADC. If the users UPN's are different and there is a trust between the domains then SSO will work.
