In OpenShift guide, steps for SAML adapter doesn't work. 

• certificates generated like in documentation didn't works to me. I think they should be created like this:

  openssl req -subj '/CN=test.keycloak.org/O=Test Keycloak./C=US' -newkey rsa:2048 -nodes -keyout key.pem -x509 -days 365 -out certificate.pem
  

  oc create secret tls example-tls-secret --cert certificate.pem --key key.pem
  

• in heml.yaml for SAML should used example-tls-secret instead of the saml-app-secret
• wrong base layer in the pom.xml
  • cloud-server -> cloud-default-config

Then I get error message

The required mechanism 'KEYCLOAK-SAML' is not available in mechanisms [BASIC, CLIENT_CERT, DIGEST, FORM] from the HttpAuthenticationFactory."

this mean the SAML adapter is not installed or configured. So in the guide is missing something.
