Kerberizing a HDP 2.5 with Ambari 2.4.1 using AD

jmlero — Wed, 09 Nov 2016 17:06:50 GMT

Hi all,

I recently configured a cluster with HDP 2.5 and Ambari 2.4.1. Now I am trying to configure kerberos using an existing AD which is still used by another cluster with HDP 2.4 (I want to have both clusters running at the same time).

I am following this guide:

https://docs.hortonworks.com/HDPDocuments/Ambari-2.2.1.0/bk_Ambari_Security_Guide/content/_launching_the_kerberos_wizard_automated_setup.html

But I always obtain the following error when installing:

Error message: Failed to connect to KDC - Failed to communicate with the Active Directory at ldap://192.168.0.2: simple bind failed: 192.168.0.2:389
Update the KDC settings in krb5-conf and kerberos-env configurations to correct this issue.

Any idea?

Thanks in advance

@Jose Molero

Was the test connection successful in Ambari UI for KDC ?

Also can you make sure you have correct file in place for /etc/krb5.conf

Hi @Sagar Shimpi, yes the test connection was successful. And also I have the krb5.conf file at /etc/
