If you are using FreeIPA LDAP, use this in your configuration.yml instead of the file authentication.
This config is using the 'authelia' user - so you will need to create one in FreeIPA
Additionally read through this config and everywhere you see 'dc=domain' be sure to update that with your site - aka ibracorp as the apex domain for ibracorp.io -- i SUSPECT that you would need to adjust the 'dc=com' to dc=org or dc=io pending your top level domain
