Kerberos authentication from windows machine?

avatar
Rising Star

Hello !

 

After some work I finished setting up Cloudera + MIT Kerberos + Windows AD.

 

from linux machine, I'm able to run "kinit ben@WIN-REALM" and then access hadoop or visit namenode webadmin. Of course I did configure SPNEGO on the web browser.

 

However, after logging in to my windows machine, which authenticate through windows AD, I can't access namenode webadmin which is at http://namenode:50070.

I tried running kinit from CMD but nothing changes.

this is what i get when i visit namenode webadmin.

 

HTTP ERROR 403

Problem accessing /index.html. Reason:

    GSSException: Defective token detected (Mechanism level: GSSHeader did not find the right tag)

 

what extra configuration do i need to do on windows to access hadoop webadmin page?

 

thank you!

Ben

Hey sparamas,

 

How did you over come the below error and successfully executed the ksetup commands:

 

Failed to create Kerberos key: 5 (0x5)
Failed to open Kerberos Key: 0x5
Failed /AddKdc : 0xc0000001

 

Thanks

Could you run the administrator cmd not a normal one?

From your error, I think you have not enough privilege to run these commands.
