privacyIDEA provider for Keycloak

This provider allows you to use privacyIDEA's 2FA with Keycloak.
We added a detailed how-to on our blog.

Download

• Check our latest releases.
• Download the PrivacyIDEA-Provider.jar for your keycloak version.

Installation

Make sure to pick the correct jar for your keycloak version from the releases page!

Keycloak >= 17

• Keycloak has to be shut down
• Move the jar file into the providers directory
• Go to bin and run kc.sh build (or the batch file on windows)
• Start keycloak again

Keycloak <= 16

• Move the packed jar file into your deployment directory standalone/deployment.
• Optional: Move the template privacyIDEA.ftl to themes/base/login. NOTE: For releases from version 0.6 onward, the template will be deployed automatically, so this step can be skipped.

Now you can enable the execution for your auth flow.
If you set the execution as 'required', every user needs to login with a second factor.

Configuration

The different configuration parameters that are available on the configuration page of the execution are explained in the following table:

Configuration	Explanation
privacyIDEA URL	The URL of your privacyIDEA server, which must be reachable from the keycloak server.
Realm	This realm will be appended to all requests to privacyIDEA. Leave empty to use the privacyIDEA default realm.
Verify SSL	You can choose if Keycloak should verify the SSL certificate from privacyIDEA. Please do not uncheck this in a productive environment!
Preferred Login Token Type	Select the token type for which the UI should be first shown. This only matters if such token was triggered before. The UI defaults to OTP mode. This can be overwritten by the policy in privacyIDEA.
Enable trigger challenge	Enable if challenges should be triggered beforehand using the provided service account. This is mutually exclusive to sending the password and takes precedence.
Service account	The username of the service account to trigger challenges or enroll tokens. Please make sure, that the service account has the correct rights.
Service account password	The password of your service account.
Service account realm	Specify a separate realm for the service account if needed. If the service account is in the same realm as the users, it is sufficient to specify the realm in the config parameter above.
Send password	Enable if the password that was used to authenticate with keycloak in the first step should be sent to privacyIDEA prior to the authentication. Can be used to trigger challenges. Mutually exclusive to trigger challenge.
Send static pass	Enable if the configured static pass should be sent to privacyIDEA prior to the authentication. Can be used to trigger challenges. If trigger challenge or send password is enabled, this will be ignored.
Static pass	The static password for send static pass. Can also be empty to send an empty password.
Included groups	Keycloak groups that should be included to 2FA. Multiple groups can be specified, separated with ','. NOTE: If both included and excluded are configured, the excluded setting will be ignored!
Excluded groups	Keycloak groups that should be excluded from 2FA. Multiple groups can be specified, separated with ','.
Forward headers	Set the headers which should be forwarded to privacyIDEA. If the header does not exist or has no value, it will be ignored. The headers names should be separated with ','.
OTP length	If you want to turn on the form-auto-submit function after x number of characters are entered into the OTP input field, set the expected OTP length.
Enable token enrollment	If the current user does not have a token yet, it can be enrolled. The service account has to be set up. Starting in privacyIDEA server version 3.8, token enrollment can be done via challenge-response and centrally managed in the server. That is the preferred way of token enrollment while logging in. This feature is therefore deprecated and will be removed in a future version.
Enrollment token type	Select the token type for the token enrollment.
Poll in browser	Enable this to do the polling for accepted push requests in the user's browser. When enabled, the login page does not refresh when checking for successful push authentication. CORS settings for privacyidea can be adjusted in etc/apache2/sites-available/privacyidea.conf.
URL for poll in browser	Optional. If poll in browser should use a deviating URL, set it here. Otherwise, the general URL will be used.
Push refresh interval	Interval in seconds to check if the push token is confirmed. This can be a comma separated list where the last value will be repeated. Default: 4,2,2,2,3.
Enable logging	Enable this to have the privacyIDEA Keycloak provider write log messages to the keycloak log file.

Manual build with source code

• First, the client submodule has to be build using maven: mvn clean install in java-client.
