Query, Visualize, and Share live HCL Domino Data in Redash

Redash is a collaboration tool that lets you query, visualize, and share your data. When paired with CData Connect Cloud, Redash gets access to live HCL Domino data. This article demonstrates how to connect to HCL Domino using Connect Cloud and work with live HCL Domino data in Redash.

CData Connect Cloud provides a pure SQL Server interface for HCL Domino, allowing you to query data from HCL Domino without replicating the data to a natively supported database. Using optimized data processing out of the box, CData Connect Cloud pushes all supported SQL operations (filters, JOINs, etc.) directly to HCL Domino, leveraging server-side processing to return the requested HCL Domino data quickly.

Configure HCL Domino Connectivity for Redash

Connectivity to HCL Domino from Redash is made possible through CData Connect Cloud. To work with HCL Domino data in Redash, we start by creating and configuring a HCL Domino connection.

1. Log into Connect Cloud, click Connections and click Add Connection
2. Select "HCL Domino" from the Add Connection panel
3. Enter the necessary authentication properties to connect to HCL Domino.

   Connecting to Domino

   To connect to Domino data, set the following properties:

   • URL: The host name or IP of the server hosting the Domino database. Include the port of the server hosting the Domino database. For example: http://sampleserver:1234/
   • DatabaseScope: The name of a scope in the Domino Web UI. The driver exposes forms and views for the schema governed by the specified scope. In the Domino Admin UI, select the Scopes menu in the sidebar. Set this property to the name of an existing scope.

   Authenticating with Domino

   Domino supports authenticating via login credentials or an Azure Active Directory OAuth application:

   Login Credentials

   To authenticate with login credentials, set the following properties:

   • AuthScheme: Set this to "OAuthPassword"
   • User: The username of the authenticating Domino user
   • Password: The password associated with the authenticating Domino user

   The driver uses the login credentials to automatically perform an OAuth token exchange.

   AzureAD

   This authentication method uses Azure Active Directory as an IdP to obtain a JWT token. You need to create a custom OAuth application in Azure Active Directory and configure it as an IdP. To do so, follow the instructions in the Help documentation. Then set the following properties:

   • AuthScheme: Set this to "AzureAD"
   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • OAuthClientId: The Client ID obtained when setting up the custom OAuth application.
   • OAuthClientSecret: The Client secret obtained when setting up the custom OAuth application.
   • CallbackURL: The redirect URI defined when you registered your app. For example: https://localhost:33333
   • AzureTenant: The Microsoft Online tenant being used to access data. Supply either a value in the form companyname.microsoft.com or the tenant ID.

     The tenant ID is the same as the directory ID shown in the Azure Portal's Azure Active Directory > Properties page.

4. Click Create & Test
5. Navigate to the Permissions tab in the Add HCL Domino Connection page and update the User-based permissions.

Add a Personal Access Token

If you are connecting from a service, application, platform, or framework that does not support OAuth authentication, you can create a Personal Access Token (PAT) to use for authentication. Best practices would dictate that you create a separate PAT for each service, to maintain granularity of access.

1. Click on your username at the top right of the Connect Cloud app and click User Profile.
2. On the User Profile page, scroll down to the Personal Access Tokens section and click Create PAT.
3. Give your PAT a name and click Create.
4. The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.

Connect to HCL Domino from Redash using Connect Cloud

To establish a connection from Redash to CData Connect Cloud using the SQL Server API, follow these steps.

1. Log into Redash.
2. Click the settings widget on the top right.
3. Click New Data Source.
4. Select Microsoft SQL Server as the Data Source Type.
5. On the configuration tab, set the following properties:
   • Database Name: enter the Connection Name of the CData Connect Cloud data source you want to connect to (for example, Salesforce1).
   • Server: enter the virtual SQL Server host name (tds.cdata.com)
   • User: enter your CData Connect Cloud username. This is displayed in the top-right corner of the CData Connect Cloud interface. For example, [email protected].
   • Password: enter the PAT you generated on the Settings page.
   • Port: enter 14333
6. Click Create.
7. Click Test Connection to ensure that the connection is configured properly.
