Configure IPA Server to share users' account in your local network

Configure IPA Server to share users' account in your local network.
[1]	Install FreeIPA.

[root@dlp ~]#  yum -y install ipa-server bind bind-dyndb-ldap

[2]	Setup FreeIPA Server.

[root@dlp ~]#  vi /etc/hosts # add own IP 10.0.0.30 dlp.server.world dlp [root@dlp ~]#  ipa-server-install --setup-dns  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) To accept the default shown in brackets, press the Enter key. # setup DNS (existing BIND settings is over-written) Existing BIND configuration detected, overwrite? [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. # confirm the hostname and Enter Server host name [dlp.server.world]: The domain name has been determined based on the host name. # confirm the domain name and Enter Please confirm the domain name [server.world]: The kerberos protocol requires a Realm name to be defined. This is typically the domain name converted to uppercase. # confirm realm name and Enter Please provide a realm name [SERVER.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. # Directory Manager's password 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's password IPA admin password: Password (confirm): # answer with yes or no for setting DNS forwarder Do you want to configure DNS forwarders? [yes]: Enter the IP address of DNS forwarder to use, or press Enter to finish. # specify DNS forwarder's IP if you set DNS forwarder Enter IP address for a DNS forwarder:  10.0.0.10 DNS forwarder 10.0.0.10 added # Enter with empty if DNS forwarder is OK Enter IP address for a DNS forwarder: # answer with yes or no for setting reverse zone Do you want to configure the reverse zone? [yes]: # reverse zone name if you set reverse zone Please specify the reverse zone name [0.0.10.in-addr.arpa.]: The IPA Master Server will be configured with: Hostname: dlp.server.world IP address: 10.0.0.30 Domain name: server.world Realm name: SERVER.WORLD BIND DNS server will be configured to serve IPA domain with: Forwarders: 10.0.0.10 Reverse zone: 0.0.10.in-addr.arpa. # confirm settings and proceed with "yes" Continue to configure the system with these values? [no]:  yes The following operations may take some minutes to complete. Please wait until the prompt is returned. Configuring NTP daemon (ntpd) ... ... ... ============================================================================== 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.
