Setup RHEVM Identity Management With IPA

The directory servers supported for use with Red Hat Enterprise Virtualization 3.3 are:

  • Active Directory
  • Identity Management ( IDM)
  • Red Hat Directory Server 9 ( RHDS 9)
  • OpenLDAP    

From this article,you'll learn following:

  • How to setup master IPA
  • How to setup slave IPA
  • How to attach a directory server to the RHEVM

Install IPA packages on master and slave

[root@ipa ~]# yum -y install ipa-server bind bind-dyndb-ldap firefox xorg-x11-xauth
[root@slave ~]# yum -y install ipa-server bind bind-dyndb-ldap firefox xorg-x11-xauth

Configure master IPA server

[root@ipa ~]# ipa-server-install --setup-dns --forwarder=172.16.255.10
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)
  * Configure DNS (bind)
To accept the default shown in brackets, press the Enter key.
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.
Server host name [ipa.xzxj.edu.cn]:
Warning: skipping DNS resolution of host ipa.xzxj.edu.cn
The domain name has been determined based on the host name.
Please confirm the domain name [xzxj.edu.cn]:
The kerberos protocol requires a Realm name to be defined.
This is typically the domain name converted to uppercase.
Please provide a realm name [XZXJ.EDU.CN]:
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):
Do you want to configure the reverse zone? [yes]:
Please specify the reverse zone name [255.16.172.in-addr.arpa.]:
Using reverse zone 255.16.172.in-addr.arpa.
The IPA Master Server will be configured with:
Hostname:      ipa.xzxj.edu.cn
IP address:    172.16.255.16
Domain name:   xzxj.edu.cn
Realm name:    XZXJ.EDU.CN
BIND DNS server will be configured to serve IPA domain with:
Forwarders:    172.16.255.10
Reverse zone:  255.16.172.in-addr.arpa.
Continue to configure the system with these values? [no]: yes

Restarting the web server
==============================================================================
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 certificate stored in /root/cacert.p12
This file is required to create replicas. The password for this
file is the Directory Manager password

After configure,you need to get a kerberos ticket:

[root@ipa ~]# kinit admin
Password for [email protected]:
[root@ipa ~]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: [email protected]
Valid starting     Expires            Service principal

  Default SELinux user: unconfined_u:s0-s0:c0.c1023
  Default PAC types: MS-PAC

Testing the replication

Login in to ipa.xzxj.edu.cn and add a new user:

[root@ipa ~]# ipa user-add candon
First name: aaaa
Last name: bb
-------------------
Added user "candon"
-------------------
  User login: candon
  First name: jacky
  Last name: lee
  Full name: jacky lee
  Display name: jacky lee
  Initials: jl
  Home directory: /home/candon
  GECOS field: jacky lee
  Login shell: /bin/bash

  Email address: [email protected]
  UID: 1229200001

Now,you can check if the user is really available on both servers  by following a ldapsearch command:

[root@slave ~]# ldapsearch -x -b "dc=xzxj,dc=edu,dc=cn" uid=candon

Set up a IPA client
