Hi, Following log extract shows date and hostname not logged for a log message , which is inconsistent with the logging of date/time for other messages and makes the message appear as a continuation of previous message. This was on 1.14.3 on EL6 linux . Logging is set in krb5.conf to FILE: Note: the kdc.conf has kdc_tcp_ports = "" to disable tcp . On startup krb5kdc logs: Jul 27 16:12:38 myhostname krb5kdc[26223](info): setting up network...
