Custom LoginModule is driven by Web Service's . I can see earlier on call stack that hostName and protocol can be found in LoginContext: my.security.auth.spi.DatabaseServerLoginModule.login(DatabaseServerLoginModule.java:116) sun.reflect.NativeMethodAccessorImpl.invoke0(NativeMethodAccessorImpl.java) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) java.lang.reflect.Method.invoke(Method.java:597) javax.security.auth.login.LoginContext.invoke(LoginContext.java:769) javax.security.auth.login.LoginContext.access$000(LoginContext.java:186) javax.security.auth.login.LoginContext$4.run(LoginContext.java:683) java.security.AccessController.doPrivileged(AccessController.java) javax.security.auth.login.LoginContext.invokePriv(LoginContext.java:680) javax.security.auth.login.LoginContext.login(LoginContext.java:579) org.jboss.security.plugins.JaasSecurityManager.defaultLogin(JaasSecurityManager.java:603) org.jboss.security.plugins.JaasSecurityManager.authenticate(JaasSecurityManager.java:537) org.jboss.security.plugins.JaasSecurityManager.isValid(JaasSecurityManager.java:344) org.jboss.web.tomcat.security.JBossSecurityMgrRealm.authenticate(JBossSecurityMgrRealm.java:491) org.apache.catalina.authenticator.BasicAuthenticator.authenticate(BasicAuthenticator.java:180) org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:490) org.jboss.web.tomcat.security.JaccContextValve.invoke(JaccContextValve.java:84) org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:127) org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:102) org.jboss.web.tomcat.service.jca.CachedConnectionValve.invoke(CachedConnectionValve.java:157) org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:262) org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:583) org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:446) java.lang.Thread.run(Thread.java:619) Now I am trying to create LoginContext in CustomLoginModule::initialize(Subject subject, CallbackHandler callbackHandler, Map sharedState, Map options) { super.initialize(subject, callbackHandler, sharedState, options); this.subject = subject; try { loginContext = new LoginContext("MySP", subject, callbackHandler); } catch (LoginException ex) { Logger.getLogger(DatabaseServerLoginModule.class.getName()).log(Level.SEVERE, null, ex); } But it does not give client ip. Maybe there is some abstraction on Jboss Remote for getting client ip ? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4175908#...
