This section shows how to set up ODBC connectivity and configure DSNs on macOS.

Minimum macOS Version

The CData ODBC Driver for MariaDB driver requires macOS Sierra (10.12) or above.

Licensing the Driver

In a terminal, run the following commands to license the driver. To activate a trial, omit the <key> input.

cd "/Applications/CData ODBC Driver for MariaDB/bin"
sudo ./install-license.sh <key>

You'll be prompted for a name and password. These refer to your name and your machine's password.

Connecting to MariaDB

The Server and Port properties must be set to a MariaDB server. Optionally, Database can be set to connect to a specific database. If not set, the driver reports tables from all databases.

Azure AD

Azure AD is Microsoft’s multi-tenant, cloud-based directory and identity management service. It is user-based authentication that requires that you set AuthScheme to AzureAD.

Desktop Applications

CData provides an embedded OAuth application that simplifies authentication at the desktop. You can also authenticate from the desktop via a custom OAuth application, which you configure and register at the MariaDB console. For further information, see Creating a Custom OAuth Application.

Before you connect, set the following variables:

• InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
• Custom Azure AD applications only:
  • OAuthClientId: The client Id assigned when you registered your custom OAuth application.
  • OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.
  • CallbackURL: The redirect URI defined when you registered your custom OAuth application.

When you connect, the driver opens the MariaDB'sOAuth endpoint in your default browser. Log in and grant permissions to the application.

When the access token expires, the driver refreshes it automatically.

Headless Machines

If you need to log in to a resource that resides on a headless machine, you must authenticate on another device that has an internet browser. You can do this in either of the following ways:

• Obtain the OAuthVerifier value as described in Obtain and Exchange a Verifier Code, below.
• Install the driver on another machine and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.

After you execute either of these options, configure the driver to automatically refresh the access token on the headless machine.

Obtaining and Exchanging a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL from a machine with an internet browser, and obtain the OAuthVerifier connection property.

1. Choose one of these options:
   • If you are using the Embedded OAuth Application, click MariaDB OAuth endpoint to open the endpoint in your browser.
   • If you are using a custom OAuth application, set the following properties to create the Authorization URL:
     • InitiateOAuth: OFF.
     • OAuthClientId: The client Id assigned when you registered your application.
     • OAuthClientSecret: The client secret assigned when you registered your application.
     After the Authorization URL is established, call the getoauthauthorizationurl stored procedure with the appropriate CallbackURL. Open the URL returned by the stored procedure in a browser.

2. Log in and grant permissions to the driver. You are redirected to the callback URL, which contains the verifier code.
3. Save the value of the verifier code. Later you will set this in the OAuthVerifier connection property.

Next, exchange the OAuth verifier code for OAuth refresh and access tokens.

To obtain the OAuth authentication values, set these properties:

• InitiateOAuth: REFRESH.
• OAuthVerifier: The verifier code.
• OAuthSettingsLocation: The location of the file where the driver saves the OAuth token values that persist across connections.
• Custom applications only:
  • OAuthClientId: (custom applications only) Set this to the client Id in your custom OAuth application settings.
  • OAuthClientSecret: (custom applications only) Set this to the client secret in the custom OAuth application settings.

After the OAuth settings file is generated, re-set the following properties to connect:

• InitiateOAuth: REFRESH.
• OAuthSettingsLocation: The location containing the encrypted OAuth authentication values. Make sure this location grants read and write permissions to the driver to enable the automatic refreshing of the access token.
• Custom applications only:
  • OAuthClientId: The client Id assigned when you registered your application.
  • OAuthClientSecret: The client secret assigned when you registered your application.

Transferring OAuth Settings

Prior to connecting on a headless machine, you must create and install a connection with the driver on a device that supports an internet browser. Set the connection properties as described in "Desktop Applications" above.

After completing the instructions in "Desktop Applications", the resulting authentication values are encrypted and written to the location specified by OAuthSettingsLocation. The default filename is OAuthSettings.txt.

Once you have successfully tested the connection, copy the OAuth settings file to your headless machine.

On the headless machine, set the following connection properties to connect to data:

• InitiateOAuth: REFRESH.
• OAuthSettingsLocation: The location of your OAuth settings file. Make sure this location gives read and write permissions to the driver to enable the automatic refreshing of the access token.
• Custom applications only:
  • OAuthClientId: The client Id assigned when you registered your application.
  • OAuthClientSecret: The client secret assigned when you registered your application.

LDAP

To authenticate as an LDAP user, set AuthScheme to LDAP.

Your LDAP credentials are auto-detected by default. If you want to designate a different user and account, set the following optional properties:

• User: The user to login as.
• Password: The user's password.

Uninstalling the Driver

The easiest way to uninstall the driver is to open a terminal and run the included uninstall.sh script, located in the installation directory. For example:

cd "/Applications/CData ODBC Driver for MariaDB"
sudo ./uninstall.sh

Note: The script needs to be run from the installation directory.
