All Machines: Edit the Kerberos Client Configuration File

The /etc/krb5/krb5.conf configuration file provides information that Kerberos clients require in order to communicate with the KDC.

Edit the /etc/krb5/krb5.conf configuration file on the KDC machine, the Directory Server machine, and any client machines that will authenticate to the Directory Server using Kerberos.

The updated /etc/krb5/krb5.conf configuration file should look like the contents of the following example.
