Keycloak integration for Duo Security MFA. Provides an authentication execution for keycloak that presents a Duo iframe, to be used after primary authentication. (https://duo.com/)
You may need to modify the keycloak versions in the pom.xml to correspond to yours. I'm using 3.4.3.Final.
$ mvn clean test install
(assumes keycloak is installed to /opt/keycloak)
$ cp target/keycloak-duo-spi-jar-with-dependencies.jar /opt/keycloak/standalone/deployments/
$ cp src/main/duo-mfa.ftl /opt/keycloak/themes/base/login/duo-mfa.ftl
# restart keycloak
You need to add Duo as a trusted frame-able source to the Keycloak Content Security Policy.
Content-Security-Policy: frame-src https://*.duosecurity.com/ 'self'; ...
Since you can't modify the default Authentication Flows, make a copy of Browser. Add Duo MFA as an execution under Browser Forms.
When you hit Config you can enter your Duo ikey, skey, and apihost (get these from duo.com by adding a Web SDK app).
Then make sure to bind your Copy of Browser flow to the Browser Flow (on the Bindings tab).
