Is there anything mis-configured or need to be checked? Thank you

@jakezhang Assign getkeys permission for ranger user in ranger policy

[#3]

Thanks.

However the permissions are already assigned in the default policy: 

  cm_kms

[#4]

@jakezhang Check is  cm_kms policy is in sync 

Also, modify the Config Properties values in cm_kms as shown below 

tag.download.auth.users=kms
policy.download.auth.users=keyadmin,rangerkms

[#5]

Thank you.

You might see they are already added in the previous screenshot.

Ranger user is added as well but it did not work.

tag.download.auth.users=kms,ranger
policy.download.auth.users=keyadmin,rangerkms,ranger

[#6]

@jakezhang  Can you check is cm_kms policy is in sync after adding the ranger users to the policy

Share the screenshot of Ranger Ui => Audit => Plugins

[#7]

Thanks @Scharan 

I don't think it's in sync since the test connection failed.

[#8 · Accepted solution]

@jakezhang From the screenshot, I can see cm_kms policy is not in sync

Policy needs to be sync after ranger users is added to the policy, then only the Ranger user will be allowed to Get the keys

[#9]

Thanks, but how can I get the policy synced?

[#10]

@jakezhang Check ranger KMS logs and see what is the error while refreshing the policy
