4 GB RAM

https://bugzilla.redhat.com/show_bug.cgi?id=1436295

Prerequisite

I have created two virtual machine, since this is a development setup I will hardcode hostname and IP in /etc/hosts and manually set hostnames.

• rhel7.7-idm-master.magnuskkarlsson.local
• 192.168.122.113
• rhel7.7-idm-replica1.magnuskkarlsson.local
• 192.168.122.99

# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.7 (Maipo)

# systemctl stop firewalld; systemctl disable firewalld

# hostnamectl set-hostname rhel7.7-idm-master.magnuskkarlsson.local
# hostnamectl set-hostname rhel7.7-idm-replica1.magnuskkarlsson.local

# echo "192.168.122.113 rhel7.7-idm-master.magnuskkarlsson.local">> /etc/hosts
# echo "192.168.122.99 rhel7.7-idm-replica1.magnuskkarlsson.local">> /etc/hosts

Update Date & Time

Make sure NTP is setup and synchronized.

systemctl restart chronyd
chronyc sources
chronyc tracking
timedatectl

Installation of IDM Master (version 4.6.5)

Install IDM Master on rhel7.7-idm-master.magnuskkarlsson.local.

# yum install -y ipa-server

# ipa-server-install --domain magnuskkarlsson.local \
    --realm MAGNUSKKARLSSON.LOCAL \
    -p foo123123 -a foo123123 -U 

Installation of IDM Replica (version 4.6.5)

Install IDM Replica on rhel7.7-idm-replica1.magnuskkarlsson.local.

First install idm/ipa client and register host in idm. Then setup host as replica.

# yum install -y ipa-server

# ipa-client-install --server=rhel7.7-idm-master.magnuskkarlsson.local \
    --domain=magnuskkarlsson.local \
    --principal=admin \
    --password=foo123123 -U

# ipa-replica-install --setup-ca --principal=admin --admin-password=foo123123 -U

Test

First kerberos login on master - rhel7.7-idm-master.magnuskkarlsson.local and add a user.

# kinit admin

# ipa user-add --first="Magnus K" \
    --last=Karlsson \
    --cn="Magnus K Karlsson" \
    --principal=magnuskkarlsson \
    --password \
    --all magnuskkarlsson

# ipa user-find magnuskkarlsson

Then kerberos login on replica - rhel7.7-idm-replica1.magnuskkarlsson.local and search for user and check that user is replicated.

# kinit admin

# ipa user-find magnuskkarlsson
