## Preparation
The following placeholders will be used:
- `rancher.company` is the FQDN of the Rancher install.
- `authentik.company` is the FQDN of the authentik install.
Under _Customization_ -> _Property Mappings_, create a _SAML Property Mapping_. Give it a name like "SAML Rancher User ID". Set the SAML name to `rancherUidUsername` and the expression to the following
```python
return f"{user.pk}-{user.username}"
```
Create an application in authentik. Set the Launch URL to `https://rancher.company`, as Rancher does not currently support IdP-initiated logins.
Create a SAML provider with the following parameters:
- ACS URL: `https://rancher.company/v1-saml/adfs/saml/acs`
- Audience: `https://rancher.company/v1-saml/adfs/saml/metadata`
- Issuer: `authentik`
- Service Provider Binding: `Post`
- Property mappings: Select all default mappings and the mapping you've created above.
- Signing Certificate: Select the authentik self-signed certificate.
You can of course use a custom signing certificate, and adjust durations.
## Rancher
In Rancher, navigate to _Global_ -> _Security_ -> _Authentication_, and select ADFS.
Fill in the fields
- Display Name Field: `http://schemas.xmlsoap.org/ws/2005/05/identity/claims/name`
- User Name Field: `http://schemas.goauthentik.io/2021/02/saml/username`
- UID Field: `rancherUidUsername`
- Groups Field: `http://schemas.xmlsoap.org/claims/Group`
For the private key and certificate, you can either generate a new pair (in authentik, navigate to _Identity & Cryptography_ -> _Certificates_ and select Generate), or use an existing pair.
Copy the metadata from authentik, and paste it in the metadata field.
Click on save to test the authentication.
