How To Resolve "The required mechanism 'BASIC' is not available in mechanisms [KEYCLOAK] from the HttpAuthenticationFactory"

Question

When I tried to deploy the keycloak-quickstart app-profile-jee-vanilla project, I ran into an error message. A bit of web searching did not provide a resolution, so I thought to ask here.

Here are the steps that I followed. Three bash shells are involved.

KEYCLOAK SHELL

curl -O -L https://downloads.jboss.org/keycloak/4.1.0.Final/keycloak-4.1.0.Final.tar.gz
tar xvfz keycloak-4.1.0.Final.tar.gz
./keycloak-4.1.0.Final/bin/standalone.sh -Djboss.socket.binding.port-offset=100

WILDFLY SHELL

curl -O -L http://download.jboss.org/wildfly/11.0.0.Final/wildfly-11.0.0.Final.tar.gz
curl -O -L https://downloads.jboss.org/keycloak/4.1.0.Final/adapters/keycloak-oidc/keycloak-wildfly-adapter-dist-4.1.0.Final.tar.gz
tar xvfz wildfly-11.0.0.Final.tar.gz
cd wildfly-11.0.0.Final
tar xvfz ../keycloak-wildfly-adapter-dist-4.1.0.Final.tar.gz
cd bin
./jboss-cli.sh --file=adapter-elytron-install-offline.cli
cd ../..
./wildfly-11.0.0.Final/bin/standlone.sh

QUICKSTART SHELL

git clone https://github.com/keycloak/keycloak-quickstarts
cd keycloak-quickstarts/app-profile-jee-vanilla
mvn clean wildfly:deploy

After a few minutes of compiling and such I see the "The required mechanism 'BASIC' is not available in mechanisms [KEYCLOAK] from the HttpAuthenticationFactory" message.

Can someone point me in the direction to resolve this issue?

Answer 1

The problem, as I now see, is that the elytron adapter was installed and it should not have been. I removed the Wildfly directory. Then un-tarred the tgz file. Without doing any other configuration, I started the Wildfly server. After the server started, the wildfly:deploy maven command worked.

Answer 2

you just need to configure the following file: standalone/configuration/standalone.xml

check the link bellow: https://www.keycloak.org/docs/latest/getting_started/index.html

step 4.5

before run:

sudo mvn clean wildfly:deploy
