If you are using FreeIPA LDAP, use this in your configuration.yml instead of the file authentication.
implementation: custom
url: ldap://
start_tls: false
skip_verify: false
minimum_version: TLS1.2
base_dn: dc=domain,dc=com
username_attribute: uid
additional_users_dn: cn=users,cn=accounts
users_filter: (&({username_attribute}={input})(objectClass=person))
additional_groups_dn: cn=groups,cn=accounts
groups_filter: (&(member=uid={input},cn=users,cn=accounts,dc=domain,dc=com)(objectclass=groupofnames))
group_name_attribute: cn
mail_attribute: mail
display_name_attribute: givenName
user: uid=authelia,cn=users,cn=accounts,dc=domain,dc=com
password: "LDAPAdminUserPassword"
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 -- i SUSPECT that you would need to adjust the 'dc=com' to dc=org or dc=io pending your top level domain
