Our SSO is currently handled via keycloak, though the user accounts themselves
|
||
|
|
are stored in LDAP; keycloak just fetches them from there.
|
||
|
|
|
||
|
|
Both LDAP and Keycloak are running in lxc containers containing debian systems
|
||
|
|
rather than on nix directly (though they both run on `parsons`).
|
||
|
|
|
||
|
|
## LDAP
|
||
|
|
|
||
|
|
LDAP stores all user accounts except those that can admininster the keycloak
|
||
|
|
master realm.
|
||
|
|
|
||
|
|
It should be reachable from within keycloak's container under `10.1.2.103`; if
|
||
|
|
it is not, keycloak will return confusingly generic errors to users.
|
||
|
|
|
||
|
|
## Keycloak
|
||
|
|
|
||
|
|
Keycloak provides other services with SSO.
|
||
|
|
|
||
|
|
An admin password for the master realm should be available in [vaultwarden](pw.hacc.space);
|
||
|
|
use it to log in to the [admin console](https://auth.infra4future.de/auth/admin/master/console/).
|
||
|
|
|
||
|
|
Inside its lxc container, keycloak lives under `/opt/keycloak` and is not managed
|
||
|
|
by any kind of package manager.
|
||
|
|
|
||
|
|
Keycloak does not write any logs to systemd; either check the logs in the admin
|
||
|
|
console or take a look at `/opt/keycloak/standalone/log/server.log` within the
|
||
|
|
lxc container. Logs are rotated daily, and apparently we keep all of them, forever.
|
||
|
|
|
||
|
|
User groups are sometimes fiddly, and currently synced with nextcloud via a
|
||
|
|
script `/opt/ldap-provision-update.sh` that systemd runs regularly.
|
||
|
|
|
||
|
|
## Useful commands
|
||
|
|
- login to a container as root with a usable shell
|
||
|
|
`lxc-attach -n keycloak -- /usr/bin/sudo -i`
|
||
|
|
- restarting the keycloak and ldap containers
|
||
|
|
`lxc-stop -n keycloak && lxc-start -n keycloak`
|
||
|
|
- restarting their network bridge:
|
||
|
|
`systemctl restart lxcbr0-netdev.services`
