As you know Tomcat is able to use JAAS Login Module for Realm authentication. But if you use standard implementation you should start Tomcat with parameter -Djava.security.auth.login.config==$CATALINA_HOME/conf/jaas.config, where jaas.config is your JAAS configuration file.
So I extended JAASRealm with jaasConfigFile attribute.
package my.realm;
import org.apache.catalina.realm.JAASRealm;
/**
* This is customization of JAASRealm, created for taking ability of setting JAAS Config File via realm properties.
* @author Sergey Vinogradov
*/
public class GDJaasRealm extends JAASRealm {
private String jaasConfigFile;
public void init() {
System.setProperty("java.security.auth.login.config", jaasConfigFile);
super.init();
}
public String getJaasConfigFile() {
return jaasConfigFile;
}
public void setJaasConfigFile(String jaasConfigFile) {
this.jaasConfigFile = jaasConfigFile;
}
}
Thus you may declare this Realm at server.xml instead of org.apache.catalina.realm.JAASRealm
<Realm className="my.realm.GDJaasRealm"
userClassNames="my.ldap.UserPrincipal"
roleClassNames="my.ldap.RolePrincipal"
appName="my_app"
jaasConfigFile="D:\ldap-jaas.conf"/>
