I am new to LDAP. And I did the authentication part using LDAP INITIAL_CONTEXT_FACTORY ("com.sun.jndi.ldap.LdapCtxFactory"). Code of what I did is as follows.
String url = ldap_url;
String uname = request.getUsername();
String pwd = request.getPassword();
boolean authentication = false;
boolean error = true;
String msg, attributes, search;
String ldapDn = String.format("%s%s", searchFilter,uname);
// create env for initial context
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, url);
env.put(Context.SECURITY_AUTHENTICATION, "simple");
env.put(Context.SECURITY_PRINCIPAL, ldapDn);
env.put(Context.SECURITY_CREDENTIALS, pwd);
try {
DirContext ctx = new InitialDirContext(env);
authentication = true;
error = false;
ctx.close();
} catch (Exception e) {
} finally {
if (!error) {
msg = "Login success!!!";
} else {
msg = "Authentication failed!";
}
}
Now I need to fetch the "employee_id" which returns with the LDAP result. I went through few examples in the internet and I could not make it happen. It will be great if anyone can suggest me a better way to search this attribute.
