Access Mac or Linux Systems

I’ve known lately that some users can already control their active directory credentials to access Mac or Linux systems. I want to know how do they come up with it? I heard about an identity services like Power Broker? Would that help?

PowerBroker selectively elevates privileges for applications, software installs, system tasks, scripts, control panel applets, management functions, and other application and system operations. It will definitely help.

Thanks! I already made some research on powerbrokers, specifically on those with wide range of compatibility like active directory linux. But, is there anyone who personally used beyondtrust as a supplier? Appreciate your inputs in advance.
