As explained under “Auth Modes” in the Configuration section, OAuth2 is one of the ways that you can have end users log in to Dataverse.
OAuth2 is an authentication protocol that allows systems to share user data, while letting the users control what data is being shared. When you see buttons stating “login with Google” or “login through Facebook”, OAuth2 is probably involved. For the purposes of this section, we will shorten “OAuth2” to just “OAuth.” OAuth can be compared and contrasted with Shibboleth.
Dataverse supports four OAuth providers: ORCID, Microsoft Azure Active Directory (AD), GitHub, and Google.
In addition OpenID Connect Login Options are supported, using a standard based on OAuth2.
Setting up an OAuth identity provider to work with Dataverse requires setup in two places: the provider, and the Dataverse installation.
Before OAuth providers will release information about their users (first name, last name, etc.) to your Dataverse installation, you must request a “Client ID” and “Client Secret” from them. In the case of GitHub and Google, this is as simple as clicking a few buttons and there is no cost associated with using their authentication service. ORCID and Microsoft, on the other hand, do not have an automated system for requesting these credentials, and it is not free to use these authentication services.
URLs to help you request a Client ID and Client Secret from the providers supported by Dataverse are provided below. For all of these providers, it’s a good idea to request the Client ID and Client secret using a generic account, perhaps the one that’s associated with the :SystemEmail you’ve configured for Dataverse, rather than your own personal Microsoft Azure AD, ORCID, GitHub, or Google account:
Each of these providers will require the following information from you:
dataverse.siteUrl JVM option mentioned in the Configuration section) appended with /oauth2/callback.xhtml such as https://dataverse.example.edu/oauth2/callback.xhtml.When you are finished you should have a Client ID and Client Secret from the provider. Keep them safe and secret.
As explained under “Auth Modes” in the Configuration section, available authentication providers are stored in the authenticationproviderrow database table and can be listed with this command:
curl http://localhost:8080/api/admin/authenticationProviders
We will POST a JSON file containing the Client ID and Client Secret to this authenticationProviders API endpoint to add another authentication provider. As a starting point, you’ll want to download the JSON template file matching the provider you’re setting up:
Here’s how the JSON template for GitHub looks, for example:
{
"id":"github",
"factoryAlias":"oauth2",
"title":"GitHub",
"subtitle":"",
"factoryData":"type: github | userEndpoint: NONE | clientId: FIXME | clientSecret: FIXME",
"enabled":true
}
Edit the JSON template and replace the two “FIXME” values with the Client ID and Client Secret you obtained earlier. Then use curl to POST the JSON to Dataverse:
curl -X POST -H 'Content-type: application/json' --upload-file github.json http://localhost:8080/api/admin/authenticationProviders
After restarting Glassfish you should see the new provider under “Other options” on the Log In page, as described in the Account Creation + Management section of the User Guide.
By default, the Log In page will show the “builtin” provider, but you can adjust this via the :DefaultAuthProvider configuration option. For details, see Configuration.
ORCID provides a sandbox registry, which may be useful for staging, or for development installations. This template can be used for configuring this setting (this is not something you should use in a production environment):
Please note that the Prerequisites section contains an step regarding CA certs in Glassfish that must be followed to get ORCID login to work.
Once you have enabled at least one OAuth provider, existing users might want to change their login method from local to OAuth to avoid having a Dataverse-specific password. This is documented from the end user perspective in the Account Creation + Management section of the User Guide. Users will be prompted to create a new account but can choose to convert an existing local account after confirming their password.
Whereas users convert their own accounts from local to OAuth as described above, conversion in the opposite direction is performed by a sysadmin. A common scenario may be as follows:
In the example below, the user has indicated that the new email address they’d like to have associated with their account is “former.oauth.user@mailinator.com” and their user id from the authenticateduser database table is “42”. The API token must belong to a superuser (probably the sysadmin executing the command).
curl -H "X-Dataverse-key: $API_TOKEN" -X PUT -d "former.oauth.user@mailinator.com" http://localhost:8080/api/admin/authenticatedUsers/id/42/convertRemoteToBuiltIn
The expected output is something like this:
{
"status": "OK",
"data": {
"email": "former.oauth.user@mailinator.com",
"username": "jdoe"
}
}
Rather than looking up the user’s id in the authenticateduser database table, you can issue this command to get a listing of all users:
curl -H "X-Dataverse-key: $API_TOKEN" http://localhost:8080/api/admin/authenticatedUsers
Per above, you now need to tell the user to use the password reset feature to set a password for their local account.
