Enabling the beneath configuration will enable only MM to use AAD. The DAM Center will still remain using the default non-AAD login.
Please be aware the the templateMemberId should be the user ID of the template user, you've noted down while verifying that you met the requirements (step 3: The ID of a user of which you want all your users to look like (AAD Template User)). In my case below its 30027.
The children of azureActiveDirectory, server and client can be a bit difficult to wrap one's head around - here's some explanation:
Server: Defines the user used for creating new AAD users.
Client: Defines that the corresponding site corresponding to the chosen client ID/application ID and tenant will use AAD for logging in. The client ID of the MM must not be input into the DC's web.config's azureActiveDirectory tag - instead the MM will have its own client ID defined within its own web.config.
