We already have OD users authenticating via Active Directory, but I would like to enable authentication to a different Azure Acitve Directory domain. I see in your docs that I can just change the email address of the user and it should start authenticating with the new external provider.
My question is, though, can I continue to use BOTH external providers? I have a weird situation where some of my users may not have user accounts in both systems, so I would need to keep the original system running, as well.
