Robert Levas commented on AMBARI-12093:
---------------------------------------
[~zmarsh13], To add {{udp_preference_limit = 1}} to the krb5.conf file, you
can update the *krb5-conf template* under the *Advanced krb5-conf* section of
the *Configure Kerberos* page in the *Enable Kerberos Wizard*.
I do not believe that adding this to the default template is a good idea since
this appears to be needed in your particular installation.
> Enable Security Wizard not honoring the unchecking of the "Manage Kerberos
> client krb5.conf" check box

> Key: AMBARI-12093
> URL: https://issues.apache.org/jira/browse/AMBARI-12093
> Project: Ambari
> Issue Type: Bug
> Environment: ambari-2.1.0-1213, hdp-2.3.0.0-2450, sles11sp3
> Reporter: Zack Marsh
> Assignee: Robert Levas
> Priority: Blocker
>
> In Ambari's Enable Kerberos Wizard, in the step “Configure Kerberos” there is
> a check-box under “Advanced krb-conf” for “Manage Kerberos client krb5.conf".
> We are generating our own krb5.conf file in our Kerberos setup script,
> therefore we have been deselecting this check-box to prevent Ambari from
> overwriting our changes.
> In the last several builds of Ambari/HDP some users (using Chrome and
> Firefox) are finding that Ambari is not honoring un-checking this option, and
> overwriting the krb4.conf file. This is resulting in many failures starting
> services (Data Node and Journal Node) during the last step of the Kerberos
> Wizard.
