I'm trying to get a Custom Security Realm in Glassfish working (i tried 3.0.1 final and 3.1 B33). I read nearly all tutorials about this, but it doesn't not work on my System. I'm getting the error
Login failed: javax.security.auth.login.LoginException: unable to find LoginModule class: com.company.security.realm.CustomLoginModule
when trying to login.
Here is what i did: I created a little Maven project, which contains the needed Realm class, CustomRealm, and the corresponding LoginModule, CustomLoginModule. My pom.xml:

My Custom Realm class:
package com.company.security.realm;
import com.sun.appserv.security.AppservRealm;
import com.sun.enterprise.security.auth.realm.BadRealmException;
import com.sun.enterprise.security.auth.realm.InvalidOperationException;
import com.sun.enterprise.security.auth.realm.NoSuchRealmException;
import com.sun.enterprise.security.auth.realm.NoSuchUserException;
import java.util.Enumeration;
import java.util.Properties;
import java.util.Vector;
public class CustomRealm extends AppservRealm
{
Vector<String> groups = new Vector<String>();
private String jaasCtxName;
private String startWith;
@Override
public void init(Properties properties)
throws BadRealmException, NoSuchRealmException {
jaasCtxName = properties.getProperty("jaas-context", "customRealm");
startWith = properties.getProperty("startWith", "z");
groups.add("dummy");
}
@Override
public String getAuthType()
{
return "Custom Realm";
}
public String[] authenticate(String username, char[] password)
{
// if (isValidLogin(username, password))
return (String[]) groups.toArray();
}
@Override
public Enumeration getGroupNames(String username)
throws InvalidOperationException, NoSuchUserException
{
return groups.elements();
}
@Override
public String getJAASContext()
{
return jaasCtxName;
}
public String getStartWith()
{
return startWith;
}
}
My LoginModule class:
package com.company.security.realm;
import com.sun.appserv.security.AppservPasswordLoginModule;
import com.sun.enterprise.security.auth.login.common.LoginException;
import java.util.Set;
import org.glassfish.security.common.PrincipalImpl;
public class CustomLoginModule extends AppservPasswordLoginModule
{
@Override
protected void authenticateUser() throws LoginException
{
_logger.info("CustomRealm : authenticateUser for " + _username);
final CustomRealm realm = (CustomRealm)_currentRealm;
if ( (_username == null) || (_username.length() == 0) || !_username.startsWith(realm.getStartWith()))
throw new LoginException("Invalid credentials");
String[] grpList = realm.authenticate(_username, getPasswordChar());
if (grpList == null) {
throw new LoginException("User not in groups");
}
_logger.info("CustomRealm : authenticateUser for " + _username);
Set principals = _subject.getPrincipals();
principals.add(new PrincipalImpl(_username));
this.commitUserAuthentication(grpList);
}
}
I compiled this Maven project and copyied the resulting JAR-file to the Glassfish/lib directory. Then i added the Security Realm "customRealm" to my Glassfish with asadmin:
asadmin create-auth-realm
--classname com.company.security.realm.CustomRealm
--property jaas-context=customRealm:startWith=a customRealm
I also referenced the LoginModule class for the JAAS context of my Custom Realm, therefore i inserted this into the login.conf of my domain:
customRealm {
com.company.security.realm.CustomLoginModule required;
};
Although this LoginModule SHOULD BE on the Glassfish classpath, as it's classfile is packaged in the JAR that i put into the Glassfish/lib-dir, it cannot be found when i try to login. For login, i build a simple JSF-project, which calls the HttpServletRequest-login-method of Servlet 3.0. When trying to login i'm getting the following Exception:
2010-12-24T14:41:31.613+0100|WARNING|glassfish3.0.1|
javax.enterprise.system.container.web.com.sun.web.security|_ThreadID=25;
_ThreadName=Thread-1;|Web login failed: Login failed:
javax.security.auth.login.LoginException: unable to find LoginModule class:
com.company.security.realm.CustomLoginModule
Anybody got an idea what i can do that Glassfish loads the LoginModule-class?
