==============================================================================
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 certificates stored in /root/cacert.p12
These files are required to create replicas. The password for these
files is the Directory Manager password

[3] Check fungsi dari IPA Server

Check terlebih dahulu bahwa Kerberos terinstall dengan benar dengan mencoba menginisialisasi token Kerberos untuk pengguna admin.

[root@ipa ~]# kinit admin
Password for admin@IPA.ZOTMA.CO.ID: 
[root@ipa ~]# klist 
Ticket cache: KEYRING:persistent:0:0
Default principal: admin@IPA.ZOTMA.CO.ID

Valid starting Expires Service principal
11/01/18 15:55:36 12/01/18 15:55:31 krbtgt/IPA.ZOTMA.CO.ID@IPA.ZOTMA.CO.ID

Ok, step yang terakhir verifikasi bahwa server IPA berfungsi dengan benar

[root@ipa ~]# ipa user-find admin
--------------
1 user matched
--------------
 User login: admin
 Last name: Administrator
 Home directory: /home/admin
 Login shell: /bin/bash
 Principal alias: admin@IPA.ZOTMA.CO.ID
 UID: 315600000
 GID: 315600000
 Account disabled: False
----------------------------
Number of entries returned 1
----------------------------

[4] Konfigurasi Firewall Server

firewall-cmd --add-service={ssh,dns,freeipa-ldap,freeipa-ldaps} --permanent 
success

firewall-cmd --reload 
success

[5] Masuk ke url IPA

Untuk check autentikasi nya bisa menggunakan skenario ini Web authentication menggunakan LDAP ( CentOS )

Untuk mengenali DN ldap nya bisa menggunakan cara seperti di bawah ini :

[root@ipa ~]# ldapsearch -x uid=nama
# extended LDIF
#
# LDAPv3
# base <dc=ipa,dc=zotma,dc=co,dc=id> (default) with scope subtree
# filter: uid=nama
# requesting: ALL
#

# nama, users, compat, ipa.zotma.co.id
dn: uid=nama,cn=users,cn=compat,dc=ipa,dc=zotma,dc=co,dc=id
objectClass: posixAccount
objectClass: ipaOverrideTarget
objectClass: top
gecos: nama saya
cn: nama saya
uidNumber: 315600005
gidNumber: 315600005
loginShell: /bin/sh
homeDirectory: /home/nama
ipaAnchorUUID:: OklQQTppcGEuYnJpc3lhcmlhaC5jby5pZDoxNjg2NTIxNi1mN2ExLTExZTctOW
 RmMC0wMDAxYTRhYWNjMWI=
uid: nama

# nama, users, accounts, ipa.zotma.co.id
dn: uid=nama,cn=users,cn=accounts,dc=ipa,dc=zotma,dc=co,dc=id
displayName: nama saya
uid: nama
objectClass: top
objectClass: person
objectClass: organizationalperson
objectClass: inetorgperson
objectClass: inetuser
objectClass: posixaccount
objectClass: krbprincipalaux
objectClass: krbticketpolicyaux
objectClass: ipaobject
objectClass: ipasshuser
objectClass: ipaSshGroupOfPubKeys
objectClass: mepOriginEntry
loginShell: /bin/sh
initials: ns
gecos: nama saya
sn: saya
homeDirectory: /home/nama
givenName: nama
cn: nama saya
uidNumber: 315600005
gidNumber: 315600005

# search result
search: 2
result: 0 Success

# numResponses: 3
# numEntries: 2

Setelah tau DN nya sebagai contoh sudah di beri tanda Bold

cn=users,cn=accounts,dc=ipa,dc=zotma,dc=co,dc=id

lalu tambahkan DN di atas ke dalam konfigurasi, dan lakukan login autentikasi.

Catatan : FreeIPA di atas tidak setup DNS, hanya untuk authentication LDAP user.

Install + Konfigurasi PowerDNS (dengan menggunakan MariaDB) dan PowerAdmin di CentOS 7

PowerDNS adalah DNS yang dikonfigurasi dengan berbagai backend seperti menggunakan relasional database, file zona seperti BIND atau algoritma load balancing / failover. Untuk installasi dan konfigurasinya akan kita bahas di halaman ini :

[1] Install dan Enable EPEL repository

# yum install epel-release -y

[2] Install MariaDB

yum install mariadb mariadb-server -y

# Start dan enable service mariadb
systemctl enable mariadb.service
Created symlink from /etc/systemd/system/multi-user.target.wants/mariadb.service to /usr/lib/systemd/system/mariadb.service.

systemctl start mariadb


# Setup MariaDB

# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
 SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
you haven't set the root password yet, the password will be blank,
so you should just press enter here.

Enter current password for root (enter for none): 
OK, successfully used password, moving on...

Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Set root password? [Y/n] y
New password: 
Re-enter new password: 
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.

Remove anonymous users? [Y/n] y
 ... Success!

Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.

Disallow root login remotely? [Y/n] y
 ... Success!

By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.

Remove test database and access to it? [Y/n] y
 - Dropping test database...
 ... Success!
 - Removing privileges on test database...
 ... Success!

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] y
 ... Success!

Cleaning up...

All done! If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
