Hi Masato As Ryan rightly mentioned above, Ranger is about Authorisation and not Authentication. The HTTP 401 Error you see is due to Authentication failure and not Authorization failure.
So you should be checking https://atlas.apache.org/index.html#/Authentication and configuring at least one of `*atlas.authentication.method`* to true. It could be one of *kerberos, ldap, file or keycloak* >From your above email I could see that you have set atlas.authentication.method to false. Due to this, Atlas has no way to deduce which auth mode to use and the 401 error you see is most likely due to that. Hope this helps -- Thanks and Regards, Umesh Padashetty On Thu, 24 Apr 2025 at 08:29, Masato Narushima <[email protected]> wrote: > Hello, Ryan san > > Thanks for the answer. > I'm afraid I don't understand it well enough, but I will check with Atlas > and Ranger about the certification and authorization. > > https://atlas.apache.org/#/ AtlasRangerAuthorizer > but it seems that my understanding is incorrect. > I am also looking for, if possible, could you please refer me to a > document that shows the relationship between Atlas and Ranger regarding > certification and authorization? > > Best regards. >
