I have an issue with the legacy conditional access app control feature, which I'm not able to find any documentation on. It's not the same feature as the one setup using conditional access policies in Azure AD.
I believe it works something like a single-sign on proxy, where the identity provider proxies through MCAS then MCAS passes the login to the service provider. This allows applying access policies within MCAS for the logins.
The apps configured has an extra option to edit the settings:
I've been using it before MCAS was acquired from Adallom.
Does anyone know what the status of this feature is? Is it still supported?
I've contacted support about it, but it didn't go anywhere.
