Setup

After starting all containers, visit the path https://{SERVER IP}:{PORT}/if/flow/initial-setup/ in your browser.
The default user is called akadmin

Manual LDAP Outpost

Manual deployment of outposts is necessary, if no integration for kubernetes or docker is provided to authentik.
Outposts are available as OCI-containers and can be deployed like any other container.
