kirby zhou commented on RANGER-3623:
------------------------------------
No, I want to pull policies from ranger in third-party services without any
authentication.
At present, if I enable anonymous/unauthenticated pulling/downloading, the
unauthenticated policy modification will also be enabled.
The ability I want to add is to allow anonymous downloads independently.

> Key: RANGER-3623
> URL: https://issues.apache.org/jira/browse/RANGER-3623
> Project: Ranger
> Issue Type: Improvement
> Components: admin
> Affects Versions: 3.0.0, 2.3.0
> Reporter: kirby zhou
> Priority: Major
> Attachments: add-downloadonly-option.patch
>
>
> Currently, we have an option ranger.admin.allow.unauthenticated.access to
> allow unauthenticated clients to perform a series of API operations. This
> option allows the client to perform both dangerous grant/revoke permission
> operation and relatively safe download operation.
> In many cases, allowing anonymous downloading of policy is not a serious risk
> problem. On the contrary, the complicated kerberos and SSL settings make it
> difficult for ranger plugin embedded in third-party services to complete the
> task of refreshing policy, which may be a bigger problem. In particular,
> refresh failure often has no obvious features for administrators to discover.
> Therefore, I suggest that ranger increase the ability to allow client to
> download policy/tag/roles anonymously.
> There are two ways to achieve it.
>
> 1. Just limit the ability of "ranger.admin.allow.unauthenticated.access=true"
> which needs to modify
> "security-admin/src/main/resources/conf.dist/security-applicationContext.xml"
> to remove dangerous operations from '
> security="none"'.
>
> 2. Add a candidate value "downloadonly" to
> "ranger.admin.allow.unauthenticated.access"
> Which needs modify ServiceRest.Java and BizUtil.java to implement the
> enhanced checking logic.
>
> I have a patch for method2
