Hi Ranger community, I'm currently working with Apache Ranger and got a bit confused by how the "user" concept is called in REST APIs and source codes. I see "Users" and "XUsers" in docs and some class names (like UserMgr and XUserMgr), and the reason for such naming is not explained anywhere. I also see "XXUsers" and "VXUsers" in source code. Could you please pour light on this and explain how these 4 terms differ? I would really appreciate it.
Thanks, Yaroslav
