I am writing a java class inside which I have two methods. One is for connecting to LDAP. The other is passing parameter and bringing the desired values.
For the connection method I want to return 1 if connection is successful and return 0 if connection failed.
here is my code:
public static boolean connection(String Prvd_url)
{
env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL,Prvd_url);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, new String("" + "\\" + ""));
env.put(Context.SECURITY_CREDENTIALS, "");
env.put(Context.REFERRAL, "ignore");
try {
ctx = new InitialDirContext(env);
return true;
}catch(NamingException ex)
{
System.out.println("Error:" + ex.toString());
return false;
}
}
At NamingException it is giving error symbol not found
I have following imports in program:
import javax.naming.Context;
import javax.naming.NamingEnumeration;
import javax.naming.directory.*;
import java.util.Hashtable;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;
try to add:
import javax.naming.NamingException;
if you are using eclipse simply press ctrl+shift+o

ctx.modifyAttributes("CN=Test1,CN=Users,DC=trial,DC=com", mods);
//"CN=Test1,CN=Users,DC=trial,DC=com"
System.out.println("Success");
}catch(AuthenticationException authEx) {
System.out.println("Active Directory Authentication failed");
authEx.printStackTrace();
}catch(Exception e){
System.out.println("Password Cannot be Changed");
e.printStackTrace();
}
}
}
When I run the code I get the following error:

Could someone help me out with this???
I'm having an issue with adding a user to my LDAP server in Java.
Here's what my code looks like

String dn = "";
String password = "";
Properties properties = new Properties();
properties.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
properties.put(Context.PROVIDER_URL, "ldap://127.0.0.1");
properties.put(Context.SECURITY_AUTHENTICATION,"none");
properties.put(Context.SECURITY_PRINCIPAL,password);
properties.put(Context.SECURITY_CREDENTIALS,dn);
// TODO code application logic here
// entry's DN
String entryDN = "uid=test_user,ou=people,dc=test123,dc=com";
// entry's attributes
Attribute cn = new BasicAttribute("cn", "tester");
Attribute uid = new BasicAttribute("uid", "tester");
Attribute gecos = new BasicAttribute("gecos", "test");
Attribute oc = new BasicAttribute("objectClass");
oc.add("top");
oc.add("person");
oc.add("organizationalPerson");
oc.add("inetOrgPerson");
DirContext ctx = null;
try {
// get a handle to an Initial DirContext
ctx = new InitialDirContext(properties);
// build the entry
BasicAttributes entry = new BasicAttributes();
entry.put(cn);
entry.put(uid);
entry.put(gecos);
entry.put(oc);
// Add the entry
ctx.createSubcontext(entryDN, entry);
// System.out.println( "AddUser: added entry " + entryDN + ".");
} catch (NamingException e) {
System.err.println("AddUser: error adding entry.\n" + e);
}
}
}
Here is the error code I get: javax.naming.AuthenticationNotSupportedException: [LDAP: error code 8 - modifications require authentication]; remaining name 'uid=test_user,ou=people,dc=test123,dc=com'
I'm not understanding why it's saying it requires authentication when I'm already binded to the server with the admin user and password.
I have create a java program that will connect to unix server1 (with user name pwd),now i need to connect another server (with username password) and execute command to push data from server 1 to server 2 using java program.
Server1 connection is working fine and i can execute some basic commands in it.

CustomTask tasks = new ExecCommand(cmd);
Result res1 = ssh1.exec(tasks);
if (res1.isSuccess) {
/*System.out.println(res1.sysout)*/;
} else {
System.out.println("Return code: " + res1.sysout);
System.out.println("error message: " + res1.error_msg);
}
ssh1.disconnect();
}
/**

*/
public static void main(String[] args) throws TaskExecFailException {
UnixConnect ob = new UnixConnect();
ob.execCommand();
}
}
In both Server i need to give username and password
This is a bit strange use case but I would do the following:
Implement bash script on server1 that would do all the job of transfering data to server2. Of course server1 has to be able to connecto server2
Use you program to invoke the bash script on server1.
i need to consume a web service developed with java web logic server, usernametoken and client certificate are used to invoke the service.
and i got the java code to call web service as below

So using WSE3.0 i try to consume the service like below

UsernameToken token = new UsernameToken("XXXX", "XXXX", PasswordOption.SendPlainText);
wse.RequestSoapContext.Security.Tokens.Add(token);
X509Certificate2 cert = new X509Certificate2(#"D:\\certificate.pfx","",X509KeyStorageFlags.MachineKeySet);
wse.ClientCertificates.Add(cert);
wse.SetPolicy("ClientPolicy");
//System.Net.ServicePointManager.CertificatePolicy =new TrustAllCertificatePolicy();
String strArg = "Param";
strArg= wse.sendData(strArg);
but i have got exception.
When this happens to me, it is usually because the time on the server and the client are too different. The security token has a validity period and if you're not in sync, it seems expired or worse, in the future.
I am facing some difficulties while listing all the users in the Active Directory. I reached to the group, but unfortunately, I could not retrieve all the users. I am looking for the user Full Names, usernames, directorate. My code is:

Can anyone help.
As it's active directory and not real ldap your talking about, can you help us with more details about ldap/active directory configuration ?
It's kind hard to help you with informations you give
Edit 1:
your problem is here no ?
while(answer.hasMore()) {
