# confirm realm name and Enter

Please provide a realm name [SRV.WORLD]:
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.

Hostname:      dlp.srv.world
IP address:
Domain name:   srv.world
Realm name:    SRV.WORLD

BIND DNS server will be configured to serve IPA domain with:
Reverse zone:  0.0.10.in-addr.arpa.

# confirm settings and proceed with "yes"

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
                UDP Ports:
                  * 88, 464: kerberos
                  * 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 certificate stored in /root/cacert.p12
This file is required to create replicas. The password for this
file is the Directory Manager password
[3] Get Kerberos tickets and change default shell.
