## What is OPNsense
|
|
|
|
From https://opnsense.org/
|
|
|
|
:::note
|
|
OPNsense is a free and Open-Source FreeBSD-based firewall and routing software. It is licensed under an Open Source Initiative approved license.
|
|
:::
|
|
|
|
:::note
|
|
This is based on authentik 2021.10.3 and OPNsense 21.7.4-amd64 installed using https://docs.opnsense.org/manual/install.html. Instructions may differ between versions.

|
|
## Preparation
|
|
|
|
The following placeholders will be used:
|
|
|
|
- `authentik.company` is the FQDN of authentik.
|
|
- `opnsense-user` is the name of the authentik Service account we'll create.
|
|
- `DC=ldap,DC=goauthentik,DC=io` is the Base DN of the LDAP Provider (default)
|
|
|
|
### Step 1
|
|
|
|
In authentik, create a service account (under _Identity & Cryptography/Users_) for OPNsense to use as the LDAP Binder.
|
|
|
|
In this example, we'll use `opnsense-user` as the Service account's username
|
|
|
|
:::note
|
|
Take note of the password for this user as you'll need to give it to OPNsense in _Step 4_.
|
|
:::
|
|
|
|
### Step 2
|
|
|
|
In authentik, create an _LDAP Provider_ (under _Resources/Providers_) with these settings:
|
|
|
|
:::note
|
|
Only settings that have been modified from default have been listed.
|
|
:::
|
|
|
|
**Protocol Settings**
|
|
- Name: LDAP
|
|
- Certificate: authentik Self-signed certificate
|
|
|
|
### Step 3
|
|
|
|
In authentik, create an application (under _Resources/Applications_) which uses this provider. Optionally apply access restrictions to the application using policy bindings.
|
|
|
|
:::note
|
|
Only settings that have been modified from default have been listed.
|
|
:::
|
|
|
|
- Name: LDAP
|
|
- Slug: ldap
|
|
- Provider: LDAP
|
|
|
|
### Step 4
|
|
|
|
In authentik, create an outpost (under _Outposts/Outposts_) of type `LDAP` that uses the LDAP Application you created in _Step 2_.
|
|
|
|
:::note
|
|
Only settings that have been modified from default have been listed.
|
|
:::
|
|
|
|
- Name: LDAP
|
|
- Type: LDAP
|
|
### Step 5
|
|
|
|
Add your authentik LDAP server to OPNsense by going to your OPNsense Web UI and clicking the `+` under _System/Access/Servers_.
|
|
|
|
Change the following fields
|
|
|
|
- Descriptive name: authentik
|
|
- Hostname or IP address: authentik.company
|
|
- Transport: SSL - Encrypted
|
|
- Bind credentials
|
|
- User DN: CN=CN=opnsense-user,OU=users,DC=ldap,DC=goauthentik,DC=io
|
|
- Password: whatever-you-set
|
|
- Base DN: DC=ldap,DC=goauthentik,DC=io
|
|
- Authentication containers: OU=users,DC=ldap,DC=goauthentik,DC=io;OU=groups,DC=ldap,DC=goauthentik,DC=io
|
|
- Extended Query: &(objectClass=user)
|
|
|
|
|
|
### Step 6
|
|
|
|
In OPNsense, go to _System/Settings/Administration_ and under _Authentication_ at the bottom of that page, add `authentik` to the Server list
|
|
|
|
|
|

|
## Notes
|
|
|
|
:::note
|
|
Secure LDAP more by creating a group for your `DN Bind` users and restricting the `Search group` of the LDAP Provider to them.
