Is it possible to connect the API Manager directly to an LDAP or active directory, so that it offers the REST APIs an authentication method?
Yes. You can configure the API Manager with multiple user stores. See Configuring User Stores.
Clustering and distributed deployment questions
For artifact governance and lifecycle management, we recommend you to use a shared WSO2 Governance Registry instance.
Is it recommended to run multiple WSO2 products on a single server?
This is not recommend in a production environment involving multiple transactions. If you want to start several WSO2 products on a single server, you must change their default ports to avoid port conflicts. See Changing the Default Ports with Offset.
How can I manage authentication centrally in a clustered environment?
This should be done in the backend services in the Application Server or WSO2 ESB.
