Spark Makerspace Network Overview
This page is intended to give you an overview of the network at Spark Makerspace.

Domain
Spark is using FreeIPA to manage host and user identities. While it's not a replacement for a Microsoft Active Directory domain controller, it get us close for the low price of free!
How to Create a New User
Point your browser to https://freeipa.spark.spork while on the Spark network and login with administrator credentials.
Once logged in, on the Identity > Users tab, click the Add button on the primary section. Enter the user's information. Spark uses a username format of first initial + last name. If this username is already in use, use full first name instead of first initial.
How to enroll a new Ubuntu machine
1. Set hostname
$ sudo hostnamectl set-hostname new-host.spark.spork
2. Install freeipa-client package
$ sudo apt install -y freeipa-client
3. Edit /etc/hosts
$ sudo vim /etc/hosts # Add FreeIPA Server IP and hostname 10.11.12.156 freeipa.spark.spork freeipa
4. Register host
# ipa-client-install --hostname=`hostname -f` \ --mkhomedir \ --server=freeipa.spark.spork \ --domain spark.spork \ --realm SPARK.SPORK
You can proceed with fixed values and no DNS discovery. It's also fine to not configure NTP.
5. Enable mkhomedir.
$ sudo bash -c "cat > /usr/share/pam-configs/mkhomedir" <<EOF Name: activate mkhomedir Default: yes Priority: 900 Session-Type: Additional Session: required pam_mkhomedir.so umask=0022 skel=/etc/skel EOF
Then run
$ sudo pam-auth-update
Ensure that "activate mkhomedir" is checked and hit enter when prompted.
