Hello fellow labberators
I would like to manage users, passwords and groups among my (mostly) ubuntu machines and as I understand it, this is what LDAP is for. I have also read that i need kerberos for authenticating nfs shares.
I will ideally be running all these services on a proxmox server but i cant figure out where to start. What order should I do them in and should i run a separate machine/ct for each or all in one?
Thanks
I propose you to try Freeipa in a docker container on one of your ubuntu server. It gives all functionality you requested and it is very easy to use. Biggest downside is that Freeipa create a Trust Authority certificate issuer and all users/computer using your internal domain will need to install the Authority Certificate to not get an error when validating personal certificate. Apart from that it is working very well.
Here are some of my notes.
You need to have a hostname set up on the server:
hostnamectl set-hostname your-server.domain.internal
You will need an entry in /etc/hosts defining the IP of the service with the hostname.
vi /etc/hosts
10.0.0.10 your-server.domain.internal
mkdir /opt/freeipa
docker run --sysctl net.ipv6.conf.all.disable_ipv6=0 --name $(hostname -s) -ti -h $(hostname -f) --read-only -v /opt/freeipa:/data -e IPA_SERVER_IP=$(ip a show dev ens18 | grep inet | awk '{ print $2 }' | sed -s 's//.*$//') freeipa/freeipa-server:rocky-9 ipa-server-install -r DOMAIN.INTERNAL -n domain.internal --no-ntp --setup-dns --forwarder=1.0.0.1 --forwarder=1.1.1.1 --reverse-zone=10.in-addr.arpa. --ip-address=$(ip a show dev ens18 | grep inet | awk '{ print $2 }' | sed -s 's//.*$//')
Here some stuff you might need to edit in the docker command:
Server IP:
-e IPA_SERVER_IP=$(ip a show dev ens18 | grep inet | awk '{ print $2 }' | sed -s 's/\/.*$//') #This line use ens18 (default for proxmox) to get the ip and use it to host the service. Change it to the IP you want for the freeipa server, same for --ip-address=
IPV6 usage:--sysctl net.ipv6.conf.all.disable_ipv6=0 # I didn't wanted to use ipv6 in my lab so you can switch it to 1 if you want ipv6 enabled
Realm domain:
-r DOMAIN.INTERNAL # Change this to whatever realm domain you want ALWAYS UPPERCASE
Domain name:
-n domain.internal # The LDAP domain to use, usually it is the realm name in lowercase
DNS parameter:
--forwarder=1.0.0.1 #These are cloudflare public dns
--forwarder=1.1.1.1 #These are cloudflare public dns
--reverse-zone=10.in-addr.arpa. #This is the reverse zone for the domain server
Thanks, i appreciate it!
Now as I started researching freeipa suddenly other options pop up such as lldap, authentik, authelia etc… now im getting confused again! Lol
