This program will set up the IPA Server.
Version 4.9.6
 
This includes:
  * Configure a stand-alone CA (dogtag) for certificate management
  * Configure the NTP client (chronyd)
  * Create and configure an instance of Directory Server
  * Create and configure a Kerberos Key Distribution Center (KDC)
  * Configure Apache (httpd)
  * Configure DNS (bind)
  * Configure SID generation
  * Configure the KDC to enable PKINIT
 
To accept the default shown in brackets, press the Enter key.
 
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 [sp-spo-ipa.juntotelecom.com.br]:
 
Warning: skipping DNS resolution of host sp-spo-ipa.juntotelecom.com.br
The domain name has been determined based on the host name.
 
Please confirm the domain name [juntotelecom.com.br]:
 
The kerberos protocol requires a Realm name to be defined.
This is typically the domain name converted to uppercase.
 
Please provide a realm name [JUNTOTELECOM.COM.BR]:
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:

Configuring client side components
This program will set up IPA client.
Version 4.9.6
 
Using existing certificate '/etc/ipa/ca.crt'.
Client hostname: sp-spo-ipa.juntotelecom.com.br
Realm: JUNTOTELECOM.COM.BR
DNS Domain: juntotelecom.com.br
IPA Server: sp-spo-ipa.juntotelecom.com.br
BaseDN: dc=juntotelecom,dc=com,dc=br
 
Configured sudoers in /etc/authselect/user-nsswitch.conf
Configured /etc/sssd/sssd.conf
Systemwide CA database updated.
Adding SSH public key from /etc/ssh/ssh_host_ed25519_key.pub
Adding SSH public key from /etc/ssh/ssh_host_ecdsa_key.pub
Adding SSH public key from /etc/ssh/ssh_host_rsa_key.pub
SSSD enabled
Configured /etc/openldap/ldap.conf
Configured /etc/ssh/ssh_config
Configured /etc/ssh/sshd_config
Configuring juntotelecom.com.br as NIS domain.
Client configuration complete.
The ipa-client-install command was successful
 
==============================================================================
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
