@Zhao Chaofeng Can you please show the /etc/ambari-server/conf/krb5JAASLogin.confconfig.

You have executed setup-security to configure jass for ambari server? Please make sure that you have set complete keytab path while configuring. It should be something like below and verify the keytab and principal by doing kinit

[root@hdp1 conf]# egrep "principal|keytab" /etc/ambari-server/conf/krb5JAASLogin.conf
    keyTab="/etc/security/keytabs/ambari.server.keytab"
    principal="ambari-server-hdp25@RAGHAV.COM"
#kinit -kt /etc/security/keytabs/ambari.server.keytab ambari-server-hdp25

Oh, I modify /etc/ambari-server/conf/krb5JAASLogin.conf corresponding with yours, and it's ok now. Thank you.

Hi All,

I am receiving the same error "Ambari Server Kerberos credentials check failed" when I try to start Ambari server. My settings are same as described above. when I am trying to kinit it is giving error" kinit: Preauthentication failed while getting initial credentials".

Please be informed that we are using Active directory for authentication.

Please let me know what to do.

Thanks
