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.
Replace every occurrence of "___default_realm___" with "EXAMPLE.COM".
Replace every occurrence of "___master_kdc___" with "kdc.example.com".
Remove the line that contains "___slave_kdcs___" as there will be only a single Kerberos server.
Replace "___domain_mapping___" with ".example.com = EXAMPLE.COM" (note the initial period in .example.com).
The updated /etc/krb5/krb5.conf configuration file should look like the contents of the following example.
#pragma ident "@(#)krb5.conf 1.2 99/07/20 SMI"
