Hi Vandana, Have look at this: https://forge.puppet.com/treydock/keycloak This is a puppet module to install (and possibly configure) Keycloak. As for SAML adapter - not that I know of, unfortunately. If you mean "should we have separate Keycloak instances for different environments, or one would suffice?" - well, that depends on your needs. Technically, there is no restriction like "one Wildfly server - one Keycloak server", so you can safely use one instance of Keycloak; you'll just have to configure three clients per application, reflecting the corresponding environment (QA, dev, testing). Please remember than if this instance goes down for some reason, this will affect all the teams. If you decide to have dedicated Keycloak instances, but you want the same users/groups everywhere, you'll probably need to configure shared external user store like LDAP or Active Directory. In production, it's common to setup a Keycloak cluster, for the purposes of high availability and load balancing. You should consider this if you expect high load and/or have requirements for high availability. Cheers, Dmitry Telegin CTO, Acutus s.r.o.
