Actual results:
The log file for this installation can be found in /var/log/ipaserver-install.log
==============================================================================
This program will set up the IPA Server.
 
This includes:
  * Configure a stand-alone CA (dogtag) for certificate management
  * Configure the Network Time Daemon (ntpd)
  * Create and configure an instance of Directory Server
  * Create and configure a Kerberos Key Distribution Center (KDC)
  * Configure Apache (httpd)
  * Configure DNS (bind)
  * Configure the KDC to enable PKINIT
 
WARNING: conflicting time&date synchronization service 'chronyd' will be disabled
in favor of ntpd
 
Warning: skipping DNS resolution of host dhcp213-66.testrelm.test
The domain name has been determined based on the host name.
 
Checking DNS domain testrelm.test., please wait ...

The IPA Master Server will be configured with:
Hostname:       IPAMASTER.testrelm.test
IP address(es): x.x.x.x
Domain name:    testrelm.test
Realm name:     TESTRELM.TEST
 
BIND DNS server will be configured to serve IPA domain with:
Forwarders:       x.x.x.x
Forward policy:   only
Reverse zone(s):  No reverse zone
