Auth0 allows you to create a custom SAML connection to Microsoft's Active Directory Federation Services. In addition to getting a bit more flexibility when configuring your mappings, the SAML Connection allows you identity provider-initiated flows (this is something that you cannot do with WS-Fed).
Step 1: Configure ADFS
To get your ADFS server ready, you'll need to:
- Add a relying party trust
- Edit your claim issuance policy
- Obtain your federation metadata
- Export the signing certificate to upload to Auth0
Add a Relying Party Trust
Begin by launching your instance of ADFS. Start the Add Relying Party Trust wizard.
On the Welcome page, choose Claims aware and click Start.
You'll see the Select Data Source page at this point. Select Enter data about the relying party manually and click Next to proceed.
On the Specify Display Name page, provide a descriptive name for your relying party (the typical format is
urn:auth0:YOUR_AUTH0_DOMAIN) and a brief description under Notes. Click Next.
Next up is the Configure Certificate page. For now, we will skip this step, so click Next to proceed.
On the Configure URL page, check the box for Enable support for the SAML 2.0 WebSSO protocol. The wizard then asks for a Relying party SAML 2.0 SSO service URL. For the time being, provide a placeholder URL; we will return to this step at a later point. Click Next.
On the Configure Identifiers page, indicate that the Relying party trust identifier is
urn:auth0:YOUR_AUTH0_DOMAIN (or whatever value you used as the display name when you started using the wizard). Click Next.
On the Choose Access Control Policy page, select Permit everyone and click Next.
Finally, review the settings you provided on the Ready to Add Trust page and click Next to save your information.
If you were successfully, you'll see a message indicating such on the Finish page. Make sure that the Configure claims issuance policy for this application checkbox is selected, and click Close.
Edit the Claim Issuance Policy
Immediately after you've closed out of the Add Relying Party Trust wizard, you'll see the Edit Claim Issuance Policy window pop up.
Click Add Rule... to launch the wizard. Use Send LDAP Attributes as Claims for your Claim rule template, and click Next to proceed.
Provide a value for the Claim rule name, such as LDAP Attributes (it can be anything you want). Choose Active Directory as your Attribute Store. Map your LDAP attributes to outgoing claim types as shown below. The only mandatory mapping you need is for the email address, but you can add as many as you'd like. Click Finish.
Back on the Edit Claim Issuance Policy window, click Apply.
You can now exit out of this window.
Obtain the Federation Metadata
To get your Federation Metadata, navigate to the following URL:
Your file will looking something like this:
Save the file for later use.
Export the Signing Certificate
Finally, you'll need to export the signing certificate from the ADFS console to upload it to Auth0 at a later point.
Using the left-hand navigation pane, go to ADFS > Service > Certificates. Select the Token-signing certificate, and right click to select View Certificate.
On the Details tab, click Copy to File....
This launches the Certificate Export Wizard. Click Next to proceed.
Choose Base-64 encoded X.509 (.CER) as the format you'd like to use. Click Next.
Provide the location to where you want the certificate exported. Click Next.
Verify that the settings for your certificate are correct. If they are, click Finish to proceed with the export process.
Step 2: Configure Auth0
Follow the tutorial on creating a SAML connection where Auth0 acts as the service provider. Where prompted, upload the signing certificate you exported from ADFS.
Step 3: Edit the Relying Party Trust
Once you have set the required parameters for creating your Auth0 connection and clicked Save, you'll see a page with instructions on creating a new relying party trust in ADFS. You'll need the following parameters:
The set of instructions presented to you after you've created your new connection will also have the exact values required for your Auth0 account/connection.
In the ADFS console, go to ADFS > Relying Party Trusts using the left-hand navigation pane. Select the relying party trust you created in step 1 and click Properties (located on the right-hand navigation pane).
Switch over to the Identifiers tab, and populate the Relying Party Identifier with the Entity ID value. Be sure to click Add to add the identifier to your list.
Switch over to the Endpoints tab, and select the placeholder URL you provided earlier. Click Edit....
Populate the Trusted URL with the Post-back URL value.
Click OK. Finally, click Apply and exit the Properties window.
Map Your Claims
You can add additional claims mappings if necessary; for assistance on which LDAP attributes map to which Outgoing Claim Type, see Connect Your App to ADFS.
Step 4: Enable and Test Your Integration.
Before you can test your Auth0-ADFS integration, you'll need to make sure that you've completed the following steps:
- Create a user for your newly-created Connection.
- Enable your Connection for at least one Application.
To test your connection, navigate to Connections > Enterprise > ADFS. Click the ADFS row (or the hamburger icon to the right) to bring up a list of your ADFS connections. Identify the one you're testing, and click the play button to test the connection.
