What does "bkr whoami" show? If you already have a valid Kerberos ticket from "kinit", the bkr client shouldn't be prompting you for your Kerberos password again.

When I check, I got below info: $ klist Ticket cache: DIR::/run/user/1000/krb5cc_137a1f16108109006add95a951d6681d/tktL2PPV2 Default principal: yanwang Valid starting Expires Service principal 07/18/13 14:45:40 07/19/13 00:45:40 krbtgt/REDHAT.COM renew until 07/18/13 14:45:40 $ bkr whoami {'username': 'yanwang', 'email_address': 'yanwang'} And I run 'sudo make bkradd' failed. I switch to root and kinit again, then re-run OK now. I'm not sure if it's relate to sudo, but it's OK now. Thanks for your quick reply, I'm closing it now.
