Super Guru

I followed the document for setting ranger kms on kerberized cluster.

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.3.2/bk_Ranger_KMS_Admin_Guide/content/ch03s02.h...

While doing test connection to default repository of Ranger KMS it gives error as shown below -

Can you please help how to resolve this ?

I found the Ranger KMS Admin Guide for HDP 2.4.0, hopefully this is what you are looking for.

From the log, looks like you are still using the username as 'keyadmin' which won't work if you have setup Kerberos. The KMSClient code looks for keyadmin@REALM if kerberos is enabled. Please set that restart the Ranger and KMS services after the change.

Uhh just saw that @vperiasamy had already replied. And that is pretty much correct. Cheers Vel !

Hi Vipin,

In my case also, user name coming as only 'keyadmin" instead of keyadmin@realm but I am giving username as

keyadmin@realm in UI:-

UNAUTHENTICATED RemoteHost:127.0.0.1 Method:GET URL:http://hostname:9292/kms/v1/keys/names?doAs=keyadmin ErrorMsg:'Authentication required'.

which property should I change for this?

please help.

Thanks in advance

Hi Vipin,

I am having the same issue, the ranger logs show "returning null list"

I am able to login into Ranger as keyadmin / password (as created in AD), I can kinit as keyadmin

I am not seeing the user in Ranger user tab, however can see the user in usersync log

Is there some other settings for AD-KDC in Ranger KMS?

Ranger KMS was setup and the cluster was kerbersized later. Does it have to be setup after kerberzing?

Thanks,

Avijeet
