You can configure your Box account to Single Sign-On (SSO) through Identity as a Service. More information on configuring Box for SSO with Identity as a Service as an Identity Provider can be found at the [Box Community Website](https://community.box.com/t5/For-Admins/Single-Sign-On-SSO-with-Box-For-Administrators/ta-p/1263#subwyidp). note This procedure was tested using previous versions of Identity as a Service and Box. Other versions of Box may require integration and configuration steps that differ from those documented in this procedure. For newer versions of Box, use this procedure as a starting point for integrating Box. In the event of other issues, contact for assistance. To integrate Box with Identity as a Service you must do the following: ## Step 1: Create a custom user attribute for Box Create a custom user attribute for Box in Identity as a Service You need to create custom user attribute to fully integrate Box and Identity as a Service. 1. Click Menu icon **>** **Members > Attributes**. The **User Attributes List** page appears. 2. Under **Custom User Attributes**, click **Plus icon**. The **Add User Attribute** dialog box appears.. 3. Enter **Box ID** as the **User Attribute Name** for the custom user attribute. 4. Optional: Check **Required** to make the user attribute mandatory. 5. Click **Add** to create the attribute. The attribute now appears in the list of **Custom User Attributes**. ## Step 2: Add Box to Identity as a Service Add Box application to Identity as a Service 1. Log into your Identity as a Service administrator account. 2. Click Menu icon **>** **Security > Applications**. The **Applications** **Lists** page appears. 3. Click **Add**. The **Select an Application Template** page appears. 4. Do one of the following: - Select **SAML Cloud Integrations** from the search drop-down list and scroll to find the application you want to add to IDaaS. - In the **Search bar**, enter a search option to filter for the application you want to add to IDaaS. 5. Click **Box**. The **Add Box** page appears. 6. Enter an **Application Name**. 7. Enter an **Application Description**. 8. Optional. Add a custom application logo. 1. Click Plus icon next to **Application Logo**. The **Upload Logo** dialog box appears. 2. Click Upload icon to select an image file to upload. 3. Browse to select your file and click **Open**. The **Upload Logo** dialog box reappears showing your selected image. 4. If required, resize your image. 5. Click **OK**. 9. Select the **Authentication Flow** that appears to users during login. 10. Click **Next**. The **General** page appears. 11. If available, use the **Upload Metadata XML** file option to auto-populate the following fields, if available in the file: - Default Assertion Consumer Service URL - Alternative Assertion Consumer URLs - Service Provider Entity ID (Issuer) - Single Logout Service URL - SAML Signing Certificate - SAML NameID Encoding Format - SAML Signature Algorithm 1. Click Upload icon to the **Upload Metadata XML** and browse to the location of the metadata file you downloaded. The **Metadata Configuration** dialog box appears. 2. If required, click **Merge with existing values** to merge new values with existing values for Alternative Assertion Consumer Services URLs and SAML attribute names. 3. Click **Save**. 12. Enter the **SAML Session Timeout** to the time when the SAML Assertion times out. The maximum is 720 minutes. 13. Enter the **Max Authentication Age (seconds)** to set the maximum amount of time that can elapse before a user is required to reauthenticate during a new login attempt. This applies for both SP-initiated and IDP-initiated login. Set this field to -1 to disable this feature. 14. If you do not have a metadata file, use the information provided in the next steps to populate the fields. 15. Enter the **Default** **Assertion Consumer Service URL** for the application. > as a Service.saml2 16. Enter the **Service Provider Entity ID (Issuer)** that is used by Identity as a Service to identify your application. > box.net 17. Leave the **Single Logout Service URL** field blank. 18. Optional. Enter the **SAML Username Parameter Name** used to identity the user ID being requested for authentication. The user ID can then be passed as a parameter, for example, Username=jdoe. 19. From the **SAML Name ID Attribute** drop-down list, select **Box Id** as the user attribute that will be used to uniquely identity a user to both Identity as a Service and your application. note If the user's email address in Identity as a Service matches exactly the user's email address in Box, then you can select **Email** as the SAML Name ID Attribute. 20. **For the** **SAML NameID Encoding Format, s**elect **email**. 21. For **SAML Response Signature Algorithm,** select the signing algorithm you want Identity as a Service to use to sign the SAML response/assertion. The type of algorithm you select depends on the requirements of the application being configured. 22. Select the **SAML Signing Certificate** from the drop-down list. 23. Optional: Select **Sign complete SAML response** to ensure the message integrity of the SAML response sent to the application during authentication. 24. Optional: Select **Respond Immediately for Unsuccessful Responses** to return to the application immediately after a login failure, rather than allow user to try again with a different userID. 25. Deselect **Enable Go Back Button** if you do not want users to be able to go back to the Box login page to log in. 26. Select **Show Default Assertion Consumer URL Service in the My Profile**. When selected, the Default Assertion Consumer URL appears in a user's My Profile page in addition to relay states and Alternative Assertion Consumer URLs. 27. Optional: Select **Encrypt SAML Assertion**. When selected the SAML Assertion is also encrypted. If you select this option, do the following: 1. From the **Encryption Method for Key** drop-down list, select either **RSA Version 1.5** or **RSA-OAEP**. RSA Version 1.5 is the default. 2. From the **Encryption Method for Data** drop-down list, select the encryption method used to encrypt data. The options are: - AES-256 (default) - AES-128 - AES-192 - Triple DES 3. In the **Encryption Certificate** field, upload the encryption certificate file. note The **Subject Domain Name** and **Certificate Expiry Date** values are populated with values from the certificate once the **Encryption Certificate** is uploaded. 28. Optional. Add **Alternative Assertion Consumer Service URLs**, as follows: 1. Click **Add**. 2. Enter a **Name**. 3. Enter a URL **Value**. 4. Select **Show in My Profile** to display the Alternative Consumer Service URL in a user's My profile page. 5. Optional. **Add an Application Logo**. 6. Click **Add**. 7. Repeat these steps to add more Alternative Assertion Consumer Service URLs. 29. Optional. Add a **Relay State** as follows: 1. Under **Relay State**, click **Add**. The **Add Relay State** dialog box appears. 2. Enter a **Name** for the relay state. 3. Enter the **Value** for the relay state. This setting specifies the application or URL that is a user is redirected to after successful authentication. 4.

Do one of the following: - Click Cloud Download icon next to the application you are integrating with Identity as a Service. - Click Ellipsis Vertical icon next to the application you are integrating with Identity as a Service and select **SAML IDP Metadata**. The **SAML Application Metadata** dialog box appears. 3. **Select the certificate to include in the SAML IDP Metadata file** from the drop-down list. 4. If applicable, **Select the domain to include in the SAML IDP Metadata** file from the drop-down list. 5. Enter the **Lifetime, in days, for the SAML IDP Metadata file**. The value must be between 2 and 730. 6. Do one of the following, as required: - Copy the **Public Endpoint** to paste into your SAML application being used Identity Provider authentication. - Click **Download**. note If you are using multiple domains, you must download each domain's metadata file separately because the values in the metadata file vary for each domain. ## Step 5: In Box, set up single-sign on for IDaaS Follow the instructions provided by Box to set up single sign-on for IDaaS. See for details and instructions: ## Step 6: Map the user's email address in the BOX ID attribute in Identity as a Service Add Box ID to Identity as a Service user attribute 1.
