Linux DSN Configuration

This section describes how to set up ODBC connectivity and configure DSNs on several Linux distributions: Debian-based systems, like Ubuntu, and Red Hat Linux platforms, like Red Hat Enterprise Linux (RHEL) and Fedora.

Minimum Linux Versions

Here are the minimum supported versions for Red Hat-based and Debian-based systems:


OS	Min. Version
Ubuntu	18.04
Debian	10
RHEL	8
Fedora	28
SUSE	15

Installing the Driver Dependencies

Run the following commands as root or with sudo to install the necessary dependencies:

Debian/Ubuntu:

apt-get install libc6 libstdc++6 zlib1g libgcc1

RHEL/Fedora:
```
yum install glibc libstdc++ zlib libgcc
```

Installing the Driver

You can use standard package management systems to install the driver.

On Debian-based systems, like Ubuntu, run the following command with root or sudo:

dpkg -i /path/to/driver/setup/MicrosoftProjectODBCDriverforUnix.deb

On systems that support the RPM package format, run the following command with root or sudo:

rpm -ivh /path/to/driver/MicrosoftProjectODBCDriverforUnix.rpm

Licensing the Driver

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

cd /opt/cdata/cdata-odbc-driver-for-microsoftproject/bin/
sudo ./install-license.sh <key>

Connecting through the Driver Manager

The driver manager loads the driver and passes function calls from the application to the driver. You need to register the driver with the driver manager and you define DSNs in the driver manager's configuration files.

The driver installation registers the driver with the unixODBC driver manager and creates a system DSN. The unixODBC driver manager can be used from Python and from many other applications. Your application may embed another driver manager.

Creating the DSN

See Using unixODBC to install unixODBC and configure DSNs. See Using the DataDirect Driver Manager to create a DSN to connect to OBIEE, Informatica, and SAS.

Connecting to Microsoft Project

To connect to the Microsoft Project data source, set these connection properties:

Url: A valid Microsoft Project Web App URL, such as http://contoso.com/sites/pwa/.
Schema: Either ODataV1 or ODataV2 (default). While ODataV2 can be used for full CRUD operations, ODataV1, which provides more granular data and exposes the custom fields, is superior for reporting purposes. For more information about the available functionality in each Schema, see Data Model.
ProjectId (optional): If the Schema is ODataV2, you can use this property to specify a default Project Id for all the operations that require one.

Authenticating to Microsoft Project

There are several authentication methods available for connecting to Microsoft Project, including the SharePoint Online Cookie Service, ADFS, OAuth, and SSO. The supported SSO identity providers are Azure AD, OneLogin, and OKTA.

SharePoint Online Cookie Service

To use your login credentials to connect to Microsoft Project on SharePoint Online, set the AuthScheme to SharePointOnlineCookies, User to your user login, and Password to your user login password.

OAuth

To enable this authentication from all Microsoft Project OAuth flows, you must create a custom OAuth application, and set AuthScheme to OAuth.

The following subsections describe how to authenticate to Microsoft Project from three common authentication flows. For information about how to create a custom OAuth application, see Creating a Custom OAuth Application. For a complete list of connection string properties available in Microsoft Project, see Connection.

Desktop Applications

To authenticate with the credentials for a custom OAuth application, you must get and refresh the OAuth access token. After you do that, you are ready to connect.

Get and refresh the OAuth access token:

InitiateOAuth: GETANDREFRESH. Used to automatically get and refresh the OAuthAccessToken.
OAuthClientId: The client Id assigned when you registered your application.
OAuthClientSecret: The client secret that was assigned when you registered your application.
CallbackURL: The redirect URI that was defined when you registered your application.

When you connect, the driver opens Microsoft Project's OAuth endpoint in your default browser. Log in and grant permissions to the application.

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

Automatic refresh of the OAuth access token:

To have the driver automatically refresh the OAuth access token:

Before connecting to data for the first time, set these connection parameters:
- InitiateOAuth: REFRESH.
- OAuthClientId: The client Id in your application settings.
- OAuthClientSecret: The client secret in your application settings.
- OAuthAccessToken: The access token returned by GetOAuthAccessToken.
- OAuthSettingsLocation: The path where you want the driver to save the OAuth values, which persist across connections.
On subsequent data connections, set:
- InitiateOAuth
- OAuthSettingsLocation

Manual refresh of the OAuth access token:

The only value needed to manually refresh the OAuth access token is the OAuth refresh token.

To manually refresh the OAuthAccessToken after the ExpiresIn period (returned by GetOAuthAccessToken) has elapsed, call the RefreshOAuthAccessToken stored procedure.
Set these connection properties:
- OAuthClientId: The Client Id in your application settings.
- OAuthClientSecret: The Client Secret in your application settings.
Call RefreshOAuthAccessToken with OAuthRefreshToken set to the OAuth refresh token returned by GetOAuthAccessToken.
After the new tokens have been retrieved, set the OAuthAccessToken property to the value returned by RefreshOAuthAccessToken. This opens a new connection.

Store the OAuth refresh token so that you can use it to manually refresh the OAuth access token after it has expired.

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:

Option 1: Obtain the OAuthVerifier value.
Option 2: Install the driver on a machine with an internet browser and transfer the OAuth authentication values after you authenticate through the usual browser-based flow.

After you execute either Option 1 or Option 2, configure the driver to automatically refresh the access token on the headless machine.

Option 1: Obtaining and Exchanging a Verifier Code

To obtain a verifier code, you must authenticate at the OAuth authorization URL as follows:

Authenticate from the machine with an internet browser, and obtain the OAuthVerifier connection property.

Set these properties:
- InitiateOAuth: OFF.
- OAuthClientId: The client Id assigned when you registered your application.
- OAuthClientSecret: The client secret assigned when you registered your application.
Call the GetOAuthAuthorizationURL stored procedure. The stored procedure returns the CallbackURL established when the custom OAuth application was registered. (See Creating a Custom OAuth Application.)

Copy this URL and paste it into a new browser tab.
Log in and grant permissions to the driver. The OAuth application redirects you the redirect URI, with a parameter called code appended. Note the value of this parameter; you will need it later, to configure the OAuthVerifier connection property.
Exchange the OAuth verifier code for OAuth refresh and access tokens. On the headless machine, to obtain the OAuth authentication values, set these properties:
- InitiateOAuth: REFRESH.
- OAuthVerifier: The noted verifier code (the value of the code parameter in the redirect URI).
- OAuthSettingsLocation: Persist the encrypted OAuth authentication values to the specified file.
- OAuthClientId: The client Id in your custom OAuth application settings.
- OAuthClientSecret: The client secret in the custom OAuth application settings.
Test the connection to generate the OAuth settings file.
You are ready to connect after you re-set these properties:
- InitiateOAuth: REFRESH.
- OAuthSettingsLocation: The file containing the encrypted OAuth authentication values. To enable the automatic refreshing of the access token, be sure that this file gives read and write permissions to the driver.
- OAuthClientId: The client Id assigned when you registered your application.
- OAuthClientSecret: The client secret assigned when you registered your application.

Option 2: Transferring OAuth Settings

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

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

Test the connection to generate the OAuth settings file, then copy the OAuth settings file to your headless machine.

To connect to data via the headless machine, set these connection properties:

InitiateOAuth: REFRESH
OAuthSettingsLocation: The path to the OAuth settings file you copied from the machine with the browser. To enable automatic refreshing of the access token, ensure that this file gives read and write permissions to the driver.
OAuthClientId: The client Id assigned when you registered your custom OAuth application.
OAuthClientSecret: The client secret assigned when you registered your custom OAuth application.

ADFS

To connect to ADFS, set the AuthScheme to ADFS, and set these properties:

User: The ADFS user.
Password: The ADFS user's password.
SSOLoginURL: The SSO provider's login url.

Example connection string:

AuthScheme=ADFS;User=username;Password=password;SSOLoginURL='https://sts.company.com';

ADFS Integrated

The ADFS Integrated flow indicates you are connecting with the currently logged in Windows user credentials. To use the ADFS Integrated flow, do not specify the User and Password, but otherwise follow the same steps in the ADFS guide above.

Supported SSO Providers

Okta

To connect to Okta, set the AuthScheme to Okta, and set these properties:

User: The Okta user.
Password: The Okta user's password.
SSOLoginURL: The SSO provider's login URL.

If you are using a trusted application or proxy that overrides the Okta client request OR configuring MFA, you must use combinations of SSOProperties to authenticate using Okta. Set any of the following, as applicable:

APIToken: When authenticating a user via a trusted application or proxy that overrides the Okta client request context, set this to the API Token the customer created from the Okta organization.
MFAType: If you have configured the MFA flow, set this to one of the following supported types: OktaVerify, Email, or SMS.
MFAPassCode: If you have configured the MFA flow, set this to a valid passcode.
If you set this to empty or an invalid value, the driver issues a one-time password challenge to your device or email. After the passcode is received, reopen the connection where the retrieved one-time password value is set to the MFAPassCode connection property.
MFARememberDevice: True by default. Okta supports remembering devices when MFA is required. If remembering devices is allowed according to the configured authentication policies, the driver sends a device token to extend MFA authentication lifetime. If you do not want MFA to be remembered, set this variable to False.

Example connection string:

AuthScheme=Okta;SSOLoginURL='https://example.okta.com/home/appType/0bg4ivz6cJRZgCz5d6/46';User=oktaUserName;Password=oktaPassword;

OneLogin

To connect to OneLogin, set the AuthScheme to OneLogin, and set these properties:

User: The OneLogin user.
Password: The OneLogin user's password.

To authenticate to OneLogin, set these SSOProperties:

OAuthClientId: The OAuthClientId, which can be obtained by selecting Developers > API Credentials > Credential > ClientId.
OAuthClientSecret: The OAuthClientSecret, which can be obtained by selecting Developers > API Credentials > Credential > ClientSecret.
Subdomain: The subdomain of the OneLogin user accessing the SSO application. For example, if your OneLogin URL is splinkly.onelogin.com, splinkly is the subdomain value.
AppId: The Id of the SSO application.
Region (optional): The region your OneLogin account resides in. Legal values are US (default) or EU.

The following example connection string uses an API key to connect to OneLogin:

AuthScheme=OneLogin;User=OneLoginUserName;Password=OneLoginPassword;SSOProperties='OAuthClientID=3fc8394584f153ce3b7924d9cd4f686443a52b;OAuthClientSecret=ca9257fd5cc3277abb5818cea28c06fe9b3b285d73d06;Subdomain=OneLoginSubDomain;AppId=1433920';

Azure AD

This configuration requires two separate Azure AD applications:

The "Microsoft Project" application used for single sign-on, and
A custom OAuth application with user_impersonation permission on the "Microsoft Project" application. (See Creating a Custom OAuth Application.)

To connect to Azure AD, set the AuthScheme to AzureAD, and set these properties:

OAuthClientId: The application Id of the connector application, listed in the Overview section of the app registration.
OAuthClientSecret: The client secret value of the connector application. Azure AD displays this when you create a new client secret.
CallbackURL: The redirect URI of the connector application. For example: https://localhost:33333.

To authenticate to Azure AD, set these SSOProperties:

Resource: The application Id URI of the Microsoft Project application, listed in the app registration's Overview section. In most cases this is the URL of your custom Microsoft Project domain.
AzureTenant: The Id of the Azure AD tenant where the applications are registered.

Example connection string:

AuthScheme=AzureAD;OAuthClientId=3ea1c786-d527-4399-8c3b-2e3696ae4b48;OauthClientSecret=xxx;CallbackUrl=https://localhost:33333;SSOProperties='Resource=;AzureTenant=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx';

Refreshing OAuth Values

The driver can refresh the temporary OAuth access tokens obtained during the browser-based OAuth authentication exchange. By default, the driver saves the encrypted tokens in the odbc.ini file corresponding to the DSN. Access to this odbc.ini file can be restricted in the case of System DSNs.

To enable the automatic token exchange, you can give the driver write access to the system odbc.ini. Or, you can set the OAuthSettingsLocation connection property to an alternate file path, to which the driver would have read and write access.

    OAuthSettingsLocation=/tmp/oauthsettings.txt

Installing Dependencies for OAuth Authentication

The OAuth authentication standard requires the authenticating user to interact with Microsoft Project, using a web-browser. If the first OAuth interaction is to be done on the same machine the driver is installed on, for example, a desktop application, the driver needs access to the xdg-open program, which opens the default browser.

To satisfy this dependency, install the corresponding package with your package manager:


Debian/Ubuntu Package	RHEL/Fedora Package	File
xdg-utils	xdg-utils	xdg-open

Set the Driver Encoding

The ODBC drivers need to specify which encoding to use with the ODBC Driver Manager. By default, the CData ODBC Drivers for Unix are configured to use UTF-16 which is compatible with unixODBC, but other Driver Managers may require alternative encoding.

Alternatively, if you are using the ODBC driver from an application that uses the ANSI ODBC API it may be necessary to set the ANSI code page. For example, to import Japanese characters in an ANSI application, you can specify the code page in the config file '/opt/cdata/cdata-odbc-driver-for-microsoftproject/lib/cdata.odbc.microsoftproject.ini':

[Driver]
AnsiCodePage = 932
