Work with SSL/LDAP Using Java
Most applications nowadays authenticate through LDAP (directory service). To set this up, first register the SSL certificate using the keytool utility, as shown below:
Register ssl certificate using keytool:
keytool -import -alias <certname> -file <filename.crt> -keystore "..yourpath\java\jre\lib\security\cacerts"
The following code shows how to connect to LDAP and display the values specific to a username:
..class name..
..
public static void main(String args[]){ String keystore = System.getProperty("" + "/lib/security/cacerts"); System.setProperty(LDAPConstants.LDAP_SSL_TRUST_STORE,keystore); try{ Hashtable env = new Hashtable(); env.put(Context.INITIAL_CONTEXT_FACTORY,"com.sun.jndi.ldap.LdapCtxFactory"); env.put(Context.PROVIDER_URL, "ldap://yourservername:636"); env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.SECURITY_PROTOCOL, "ssl"); env.put(Context.SECURITY_PRINCIPAL, "yourusername"); env.put(Context.SECURITY_CREDENTIALS, "yourpassword"); dirCtx = new InitialLdapContext(env, null); NamingEnumeration ne = null; SearchControls controls = new SearchControls(); controls.setSearchScope(SearchControls.SUBTREE_SCOPE); ne = dirCtx.search("OU=Users,DC=yourcompany, DC=com, DC=au","userName="+userName,controls); if (ne != null) { if (ne.hasMore()) { SearchResult item = (SearchResult) ne.next(); display(item.getAttributes()); } }catch(javax.naming.AuthenticationException e){ e.printStackTrace(); }catch(NamingException e) { e.printStackTrace(); } } private static void display(Attributes attr) throws NamingException{ NamingEnumeration ne = attr.getAll(); while(ne.hasMore()){ Attribute obj = (Attribute)ne.next(); System.out.println(obj.getID()+"\t"+(String)obj.get(0)); } } .... ...
