Package org.camunda.bpm.engine.rest.security.auth

Class ProcessEngineAuthenticationFilter

java.lang.Object

org.camunda.bpm.engine.rest.security.auth.ProcessEngineAuthenticationFilter

All Implemented Interfaces:

javax.servlet.Filter

public class ProcessEngineAuthenticationFilter
extends Object
implements javax.servlet.Filter

Servlet filter to plug in authentication.

Valid init-params:

Parameter	Required	Expected value
"authentication-provider"	yes	An implementation of AuthenticationProvider
"rest-url-pattern-prefix"	no	The expected servlet path. Should only be set, if the underlying JAX-RS application is not deployed as a servlet (e.g. Resteasy allows deployments as a servlet filter). Value has to match what would be the HttpServletRequest.getServletPath() if it was deployed as a servlet.
