[keycloak-user] Can Keycloak be used to secure PHP applications?

Hi All, In the Adapters section of the documentation(http://keycloak.github.io/docs/userguide/html/ch08.html#installed-applications) it says "This section defines which application types are supported and how to configure and install them" and lists some servers. I thought that since Keycloak supports SAML, I could use a SAML client library and secure any application. Is my assumption wrong? -- Thanks, Pubudu
