The error "Cannot resolve network address for KDC in requested realm while getting initial credentials" mainly pops up when you don't have your /etc/resolv.conf' or '/etc/hosts' file set up properly. Could you please verify this and also check that all your DNS servers are working fine.Each host's canonical name must be a FQDN, including the domain, and each host's IP address must reverse-resolve the canonical name. The basic thing is that your client should be able to resolve the server address ( kerberos name specified in the /etc/krb5.conf ) properly. Also please ensure that your system time is synchronized with the Kerberos server.Hosts are configured to reject responses from any KDC whose clock is not within the specified maximum clock skew ( 300 secs / 5 min ), as specified in the krb5.conf file. This directive (clockskew) must be specified in the [libdefaults] section.
Please check these and update us on the details.
