JNDI .Net implemantation - java

I've a java code which uses JNDI to acess a Directory and get user/password to login inside a samba.
What I need is a way to covnert it to .Net code. However I read this MSDN article and couldn't understand. I've tried to use DirectorySearcher class in many different ways.
There's a small piece of java code:
try {
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
env.put(Context.PROVIDER_URL, jndiServerURL);
ic = new InitialContext(env);
fileSystemProxy = (T3FileSystemProxy) ic.lookup("Credential");
}
catch (Exception e) {
e.printStackTrace();
}
Does somebody know how to implement it?

Unfortunately I couldn't implement JNDI because it's an interface for Java. I've had to get the UNC path and to authenticate using network credential.
using (new UNCPathAccess(Path.GetDirectoryName(pathPdf), username, string.Empty, password))
{
Email.Send(subject, body, email, attachments);
}

LDAP Java print debug output

When one configure application settings it always useful to show debug/output of the process.
E.g. javax.mail.Session has debug and debugOutput. Is it something similar in parameters/API for InitialDirContext/InitialLdapContext/LdapCtxFactory Java classes?
My goal is to give a user debug info if something is going wrong with LDAP connection.
P.S. Java code is trivial:
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
properties.put(Context.PROVIDER_URL, domainController);
properties.put(Context.SECURITY_AUTHENTICATION, "simple");
properties.put(Context.SECURITY_PRINCIPAL, login);
properties.put(Context.SECURITY_CREDENTIALS, password);
//initializing active directory LDAP connection
InitialDirContext dirContext = null;
try {
dirContext = new InitialDirContext(properties);
System.out.println("OK!");
} catch (NamingException e) {
//ignore auth. exception
System.out.println("Failed!!!");
e.printStackTrace();
}finally{
if(dirContext != null)
try {
dirContext.close();
} catch (NamingException e) {}
}
}
You can set the com.sun.jndi.ldap.connect.pool.debug system property to all and it should provide the information that you need.

T3 client with custom SSLSocketFactory

I have my T3 client code like this:
private InitialContext initContext() {
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
p.put(Context.PROVIDER_URL, context.providerURL);
for (Map.Entry<String, String> entry : getEnvironmentProperties().entrySet()) {
p.put(entry.getKey(), entry.getValue());
}
InitialContext res = null;
try {
res = new InitialContext(p);
} catch (NamingException e) {
e.printStackTrace();
}
return res;
}
My t3 client deployed on Tomcat (uses wlthint3client-12.1.3.jar) and trying to lookup remote bean of external system which deployed on Weblogic.
However when I trying to perform new InitialContext(p) I receive SSLHandshake exception, because it gets standart SSLSocketFactory with standart SSLConext and standart java trust store.
My question - is there any way to give to InitialContext some property which will override SSLSocketFacory. My aim is to populate my cutom trust store to this t3 client.
Changing standart trust store like this
System.setProperty("javax.net.ssl.trustStore", "pathToTrustStore");
works fine, however in case if my t3 client is used to communicate with 2 different external systems, it might be a problem in doing so.
Is there some property that I can populate?
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
**p.put("CUSTOM SSL SOCKET FACTORY, "MY CLASS");**
Problem was solved by adding few parameters on application side
export JAVA_OPTS ="$JAVA_OPTS -Djavax.net.ssl.trustStore=path/truststore.jks"
export JAVA_OPTS ="$JAVA_OPTS -Djavax.net.ssl.trustStorePassword=changeIT"

how to create a new user jazn-data.xml programmatically?

I'm using JDeveloper 11g.
I want to create a new user programmatically in 'jazn-data.xml'. Is this possible and how can I do it?
public void createWeblogicUser() {
try {
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
env.put(Context.SECURITY_PRINCIPAL, "weblogic");
env.put(Context.SECURITY_CREDENTIALS, "welcome1");
env.put(Context.PROVIDER_URL, "t3://127.0.0.1:7101");
InitialContext ctx = new InitialContext(env);
MBeanServer wls = (MBeanServer) ctx.lookup("java:comp/env/jmx/runtime");
wls.invoke(new ObjectName(" Security:Name=myrealmDefaultAuthenticator")
, "createUser"
, new Object[] {"wls_user5555", "password123","User created programmatically."}
, new String[] {"java.lang.String", "java.lang.String","java.lang.String"}
);
ctx.close();
}
catch(Exception ex) {
ex.printStackTrace();
}
}
Yes, is possible.
Technically speaking, you do not create users in jazn-data.xml, this is just a file used at development time. At runtime, you create users in weblogic.

Simple LDAP SSO auth

I have a very simple LDAP auth :
DirContext ctx = null;
try
{
logger.debug("Trying to log with LDAP");
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(javax.naming.Context.INITIAL_CONTEXT_FACTORY, ninjaProperties.get("ldapFactory"));
env.put(javax.naming.Context.PROVIDER_URL, ninjaProperties.get("ldapProvider"));
env.put(javax.naming.Context.SECURITY_AUTHENTICATION, ninjaProperties.get("ldapAuthentication"));
env.put(javax.naming.Context.SECURITY_PRINCIPAL, ninjaProperties.get("ldapDomain") + context.getParameter("login"));
env.put(javax.naming.Context.SECURITY_CREDENTIALS, context.getParameter("password"));
ctx = new InitialDirContext(env);
if(ctx != null){
logger.info( "User [" + context.getParameter("login") + "] logged in successfully." );
ctx.close();
return Results.redirect("/TermeController/consult");
}
}
catch (Exception e)
{
logger.error("LDAP Login failed : " + e.toString());
}
For now, users logg in with a form. I would like to set up an SSO auth, but i can't find a way to set it up easily.
Do i need to use something like CAS or so? Or is there a simple way?
Thx :)
SSO is quite a broad topic, I am not sure what exactly you are trying to achieve here. However if you want SSO for windows users i.e. allowing Windows users that are already authenticated against a domain controller to access your app with the same credentials you could look into WAFFLE which does exactly that.

Remote object call inside remote JVM

I'm working with weblogic Server. I was wondering if after binding an object in the JNDI context it would be possible to make remote call on this object (executing it inside the remote JVM).
In my local JVM:
Context ctx = null;
Hashtable<String, String> env = new Hashtable<String, String>();
env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL,"t3://remoteServer:7001/);
env.put(Context.SECURITY_PRINCIPAL,"");
env.put(Context.SECURITY_CREDENTIALS,"");
try {
ctx = new InitialContext(env);
MyObjectImpl obj1 = new MyObjectImpl();
ctx.bind("jndi_name", obj1);
//Now my object can be retrieve from the JNDI context under "jndi_name"
MyObjectImpl obj2 = (MyObjectImpl)ctx.lookup("jndi_name"); //lookup of object
System.out.println(obj2.method(1,2)); //call
}catch (Exception e) {
// a failure occurred
}
But the call is done locally in the client JVM and not the remote JVM.
Is there any way to counter this problem?
Regards,
Make sure you have a remote interface(using annotation #Remote) for jndi lookup.
You can see this example: http://middlewaremagic.com/weblogic/?p=5532 (search for the class “CalculatorBean.java”).
