|
|
The following placeholders will be used:
|
|
|
|

|
|

|
|
- `METADATAURL` is the url for the SAML metadata from authentik
|
|
|
|
### Step 1
|
|
|
|
In authentik, under _Providers_, create a _SAML Provider_ with these settings:

|
|
|

|
- Name: Bookstack
|
|

|
|
- Issuer: https://authentik.company
|
|
- Service Provider Binding: Post
|
|
- Audience: https://book.company/saml2/metadata
|
|
|
|
**Advanced protocol settings**
|
|
- Signing Certificate: Choose your certificate or the default authentik Self-signed Certificate
|
|
All other options as default.
|
|
|
|
|
|
|
|
### Step 2
|
|
|
|
In authentik, create an application which uses this provider. Optionally apply access restrictions to the application using policy bindings.
|
|
|
|
- Name: Bookstack
|
|
- Slug: bookstack
|
|
- Provider: Bookstack
|
|
- Launch URL: https://book.company
|
|
|
|
### Step 3
|
|
|
|
Obtain your Metadata URL from Authentik.
|
|
|
|
1. Click on the BookStack Provider
|
|
2. Click the Metadata Tab
|
|
3. Click Copy download URL (This URL is the `METADATAURL` required in Step 4)
|
|
|
|
|
|
|
|
### Step 4
|
|
|
|
Edit the `.env` file inside of the `www` folder of Bookstack.
|
|
|
|
Modify the following Example SAML config and paste incorporate into your `.env` file
|
|
|
|
```bash
|
|
# Set authentication method to be saml2
|
|
AUTH_METHOD=saml2
|
|
# Set the display name to be shown on the login button.
|
|
# (Login with <name>)
|
|
SAML2_NAME=Authentik
|
|
# Name of the attribute which provides the user's email address
|
|
SAML2_EMAIL_ATTRIBUTE=email
|
|
# Name of the attribute to use as an ID for the SAML user.
|
|
SAML2_EXTERNAL_ID_ATTRIBUTE=uid
|
|
# Name of the attribute(s) to use for the user's display name
|
|
# Can have multiple attributes listed, separated with a '|' in which
|
|
# case those values will be joined with a space.
|
|
# Example: SAML2_DISPLAY_NAME_ATTRIBUTES=firstName|lastName
|
|
# Defaults to the ID value if not found.
|
|
SAML2_DISPLAY_NAME_ATTRIBUTES=Name
|
|
# Identity Provider entityID URL
|
|
SAML2_IDP_ENTITYID=METADATAURL
|
|
# Auto-load metatadata from the IDP
|
|
# Setting this to true negates the need to specify the next three options
|
|
SAML2_AUTOLOAD_METADATA=true
|
|
|
|
```

## Notes
|
|
|
|
:::note
|
|
BookStack will attempt to match the SAML user to an existing BookStack user based on a stored external id attribute otherwise, if not found, BookStack will effectively auto-register that user to provide a seamless access experience.
