{{book.project.name}} supports SAML 2.0 for registered applications. Both POST and Redirect bindings are supported. You can choose to require client signature validation and can have the server sign and/or encrypt responses as well.
To create a SAML client go to the Clients left menu item. On this page you’ll see a Create button on the right.
This will bring you to the Add Client page.
Enter in the Client ID of the client. This is often a URL and will be the expected issuer value in SAML requests sent
by the application. Next select saml in the Client Protocol drop down box.
Ignore the Client Template listbox for now,
we’ll go over that later in this chapter.
Finally enter in the Client SAML Endpoint URL. Enter the
URL you want the {{book.project.name}} server to send SAML requests and responses to. Usually applications have only one URL for processing SAML requests.
If your application has different URLs for its bindings, don’t worry, you can fix this in the Settings tab of the client.
Click Save. This will create the client and bring you to the client Settings
tab.
- Client ID
-
This value must match the issuer value sent with AuthNRequests. {{book.project.name}} will pull the issuer from the Authn SAML request and match it to a client by this value.
- Name
-
This is the display name for the client whenever it is displayed in a {{book.project.name}} UI screen. You can localize the value of this field by setting up a replacement string value i.e. ${myapp}. See the {{book.developerguide.name}} for more information.
- Description
-
This specifies the description of the client. This can also be localized.
- Enabled
-
If this is turned off, the client will not be allowed to request authentication.
- Consent Required
-
If this is on, then users will get a consent page which asks the user if they grant access to that application. It will also display the metadata that the client is interested in so that the user knows exactly what information the client is getting access to. If you’ve ever done a social login to Google, you’ll often see a similar page. {{book.project.name}} provides the same functionality.
- Include AuthnStatement
-
SAML login responses may specify the authentication method used (password, etc.) as well as a timestamp of the login. Setting this to on will include that statement in the response document.
- Sign Documents
-
When turned on, {{book.project.name}} will sign the document using the realm’s private key.
- Sign Assertions
-
The
Sign Documentsswitch signs the whole document. With this setting the assertion is also signed and embedded within the SAML XML Auth response. - Signature Algorithm
-
Choose between a variety of algorithms for signing SAML documents.
- Canonicalization Method
-
Canonicalization method for XML signatures.
- Encrypt Assertions
-
Encrypt assertions in SAML documents with the realm’s private key. The AES algorithm is used with a key size of 128 bits.
- Client Signature Required
-
Expect that documents coming from a client are signed. {{book.project.name}} will validate this signature using the client public key or cert set up in the
SAML Keystab. - Force POST Binding
-
By default, {{book.project.name}} will respond using the initial SAML binding of the original request. By turning on this switch, you will force {{book.project.name}} to always respond using the SAML POST Binding even if the original request was the Redirect binding.
- Front Channel Logout
-
If true, this application requires a browser redirect to be able to perform a logout. For example, the application may require a cookie to be reset which could only be done via a redirect. If this switch is false, then {{book.project.name}} will invoke a background SAML request to logout the application.
- Force Name ID Format
-
If the request has a name ID policy, ignore it and used the value configured in the admin console under Name ID Format
- Name ID Format
-
Name ID Format for the subject. If no name ID policy is specified in the request or if the Force Name ID Format attribute is true, this value is used. Properties used for each of the respective formats are defined below.
- Root URL
-
If {{book.project.name}} uses any configured relative URLs, this value is prepended to them.
- Valid Redirect URIs
-
This is an optional field. Enter in a URL pattern and click the + sign to add. Click the - sign next to URLs you want to remove. Remember that you still have to click the
Savebutton! Wildcards (\*) are only allowed at the end of of a URI, i.e. http://host.com/*. This field is used when the exact SAML endpoints are not registered and {{book.project.name}} is pull the Assertion Consumer URL from the request. - Base URL
-
If {{book.project.name}} needs to link to the client, this URL would be used.
- Master SAML Processing URL
-
This URL will be used for all SAML requests and the response will be directed to the SP. It will be used as the Assertion Consumer Service URL and the Single Logout Service URL. If a login request contains the Assertion Consumer Service URL, that will take precedence, but this URL must be valided by a registered Valid Redirect URI pattern
- Assertion Consumer Service POST Binding URL
-
POST Binding URL for the Assertion Consumer Service.
- Assertion Consumer Service Redirect Binding URL
-
Redirect Binding URL for the Assertion Consumer Service.
- Logout Service POST Binding URL
-
POST Binding URL for the Logout Service.
- Logout Service Redirect Binding URL
-
Redirect Binding URL for the Logout Service.
