This section describes how to edit the DSN configuration and then authenticate and connect to Couchbase APIs.

DSN Configuration

You can use the Microsoft ODBC Data Source Administrator to edit the DSN configuration. Note that the installation process creates a both a user DSN and a system DSN, as described in Installing the Connector.

Note: The connector stores connection information in the Windows registry. To ensure that the connector can write to the registry, either run Power BI as an administrator or use a User DSN for your connection instead of a System DSN.

User DSN

Complete the following steps to edit the DSN configuration:

1. Select Start > Search, and enter ODBC Data Sources in the Search box.
2. Choose the version of the ODBC Administrator that corresponds to the bitness of your Power BI Desktop installation (32-bit or 64-bit).
3. Select the system data source and click Configure.
4. Edit the information on the Connection tab and click OK.

System DSN

Configure the system DSN the same way as the user DSN, except you will need to switch to the System DSN tab before performing Step 3.

Connecting to Couchbase

To connect to data, set the Server property to the hostname or IP address of the Couchbase server(s) you are authenticating to.

If your Couchbase server is configured to use SSL, you can enable it either by using an https URL for Server (like https://couchbase.server), or by setting the UseSSL property to True.

Couchbase Analytics

By default, the connector connects to the N1QL Query service. In order to connect to the Couchbase Analytics service, you will also need to set the CouchbaseService property to Analytics.

Couchbase Cloud

Set the following to connect to Couchbase Cloud:

• AuthScheme: Set this to Basic.
• ConnectionMode: Set this to Cloud.
• DNSServer: Set this to a DNS server. In most cases, this should be a public DNS service like 1.1.1.1 or 8.8.8.8.
• SSLServerCert: Set this to the TLS/SSL certificate to be accepted from the server. Any other certificate that is not trusted by the machine is rejected. Alternatively, set "*" to accept all certificates.

Authenticating to Couchbase

The connector supports several forms of authentication. Couchbase Cloud only accepts Standard authentication, while Couchbase Server accepts Standard authentication, client certificates, and credentials files.

Standard Authentication

To authenticate with standard authentication, set the following:

• AuthScheme: Set this to Basic.
• User: The user authenticating to Couchbase.
• Password: The password of the user authenticating to Couchbase.

Client Certificates

The connector supports authenticating with client certificates when SSL is enabled. To use client certificate authentication, set the following properties:

• AuthScheme: Set this to SSLCertificate.
• SSLClientCertType: The type of client certificate set within SSLClientCert.
• SSLClientCert: The client certificate in the format given by SSLClientCertType.
• SSLClientCertPassword (optional): The password of the client certificate, if it is encrypted.
• SSLClientCertSubject (optional): The subject of the client certificate, which, by default, is the first certificate found in the store. This is required if more than one certificate is available in the certificate store.

Credentials File

You can also authenticate using using a credentials file containing multiple logins. This is included for legacy use and is not recommended when connecting to a Couchbase Server that supports role-based authentication.

• AuthScheme: Set this to CredentialsFile.
• CredentialsFile: The path to the credentials file. Refer to Couchbase's documentation for more information on the format of this file.
