Hello Narushima-san, This is not something I have implemented myself, so forgive me if my comments are in any way misguided.
Per my understanding though, Ranger is all about *authorization*, not authentication. Ranger and Atlas should use the same *authentication* source - e.g. LDAP. That would be involved in getting users logged in in the first place. Then, *after* a user has confirmed their identity and logged in, *then* Ranger gets involved by *authorizing* what that user is allowed to see and do inside Atlas. In the Cloudera stack, we often use Apache Knox <https://knox.apache.org/> as the component to mediate between various authentication sources on the one hand (Active Directory, Okta, FreeIPA etc.) and the various big data tools on the other (Ranger, Atlas and so on). I hope this is somehow helpful.
