* 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)
To accept the default shown in brackets, press the Enter key.
Do you want to configure integrated DNS (BIND)? [no]: yes
Enter the fully qualified domain name of the computer

on which you’re setting up server software. Using the form

<hostname>.<domainname>

Example: master.example.com.
Server host name [freeipa01.redorbita.com]:
Warning: skipping DNS resolution of host freeipa01.redorbita.com

The domain name has been determined based on the host name.
Please confirm the domain name [redorbita.com]:
The kerberos protocol requires a Realm name to be defined.

This is typically the domain name converted to uppercase.
Please provide a realm name [REDORBITA.COM]: 

Certain directory server operations require an administrative user.

This user is referred to as the Directory Manager and has full access

to the Directory for system management tasks and will be added to the

instance of directory server created for IPA.

The password must be at least 8 characters long.
Directory Manager password: 

Password (confirm):
The IPA server requires an administrative user, named ‘admin’.

This user is a regular system account used for IPA server administration.
IPA admin password:

Password (confirm):
Existing BIND configuration detected, overwrite? [no]: yes

Do you want to configure DNS forwarders? [yes]: yes

Enter an IP address for a DNS forwarder, or press Enter to skip:

No DNS forwarders configured

Do you want to configure the reverse zone? [yes]: yes

Please specify the reverse zone name [1.168.192.in-addr.arpa.]:

Using reverse zone(s) 1.168.192.in-addr.arpa.
The IPA Master Server will be configured with:

Hostname:       freeipa01.redorbita.com

IP address(es): 192.168.1.80

Domain name:    redorbita.com

Realm name:     REDORBITA.COM
BIND DNS server will be configured to serve IPA domain with:

Forwarders:    No forwarders

Reverse zone(s):  1.168.192.in-addr.arpa.
Continue to configure the system with these values? [no]: yes
The following operations may take some minutes to complete.

Setup complete
Next steps:

1. You must make sure these network ports are open:

TCP Ports:

* 80, 443: HTTP/HTTPS

* 389, 636: LDAP/LDAPS

* 88, 464: kerberos

* 53: bind

UDP Ports:

* 88, 464: kerberos

* 53: bind

* 123: ntp
2. You can now obtain a kerberos ticket using the command: ‘kinit admin’

This ticket will allow you to use the IPA tools (e.g., ipa user-add)

and the web user interface.
Be sure to back up the CA certificates stored in /root/cacert.p12

These files are required to create replicas. The password for these

files is the Directory Manager password
