Howto use JaasSecurityManager mbean isValid method?

[evrim]

Hi,

I'm trying to authenticate a subject using jaassecurity manager but failed.

public void authenticate(String nick, String pass)
 throws UnauthorizedException {
 MBeanServer server = MBeanServerLocator.locateJBoss();
 String jaasMgrName = "jboss.security:service=JaasSecurityManager";
 String domainName = "java:/jaas/core";
 Principal p = new SimplePrincipal(nick);

 ObjectName jaasMgr;
 try {
 jaasMgr = new ObjectName(jaasMgrName);
 Object[] params = {domainName, p, pass.toCharArray()};
 String[] signature = {"java.lang.String", "java.security.Principal",
 "java.lang.Object"};
 Boolean valid= (Boolean) server.invoke(jaasMgr, "isValid", params, signature);
 System.err.println("result:"+valid);
 } catch (Exception e) {
 e.printStackTrace();
 }
 }

Code is executed inside a war which is also using java:/jaas/core domain. How to use isValid() method? It now returns false all the time.

I'm using standard login-config.xml with DatabaseServerLoginModule.

Tried "core" as securityDomain but result is same.
