    <p>I have implemented the features to enable, create and disable user in AD. I also need to make sure I can delete the user in AD using Java. Here below are some related code, can someone let me know how to delete the user in AD? I prefer to use the original java code to implement this.</p> <pre><code>import java.io.IOException; import java.io.UnsupportedEncodingException; import java.util.ArrayList; import java.util.Hashtable; import java.util.List; import javax.naming.Context; import javax.naming.NamingEnumeration; import javax.naming.NamingException; import javax.naming.directory.Attribute; import javax.naming.directory.Attributes; import javax.naming.directory.BasicAttribute; import javax.naming.directory.BasicAttributes; import javax.naming.directory.DirContext; import javax.naming.directory.ModificationItem; import javax.naming.directory.SearchControls; import javax.naming.directory.SearchResult; import javax.naming.ldap.Control; import javax.naming.ldap.InitialLdapContext; import javax.naming.ldap.LdapContext; import javax.naming.ldap.PagedResultsControl; import javax.naming.ldap.PagedResultsResponseControl; public class LDAPTool { /** * * @param attrs * @param propertyName * @return the value of the property. */ public static String getString(Attributes attrs, String propertyName) { String value = ""; if (null != attrs) { Attribute attr = attrs.get(propertyName); if (null != attr) { value = String.valueOf(attr); value = value.substring(value.indexOf(": ") + 2).trim(); } } return value; } /** * * @param host * @param port * @param username * @param password * @return * @return true if passed the authenticate, or else false. * @throws NamingException */ public static void authenticate(String host, int port, String username, String password) throws NamingException { LdapContext ctx = getLdapContext(host, port, username, password); if(null != ctx){ ctx.close(); } } /** * * @param host * host name or IP address * @param port * port for LDAP protocol * @param username * @param password * @return the LDAP context * @throws NamingException */ public static LdapContext getLdapContext(String host, int port, String username, String password) throws NamingException { Hashtable&lt;String, String&gt; env = new Hashtable&lt;String, String&gt;(); env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.ldap.LdapCtxFactory"); env.put(Context.PROVIDER_URL, "ldap://" + host + ":" + port); env.put(Context.SECURITY_AUTHENTICATION, "simple"); env.put(Context.SECURITY_PRINCIPAL, username); env.put(Context.SECURITY_CREDENTIALS, password); env.put("java.naming.ldap.attributes.binary", "tokenGroups"); env.put("java.naming.ldap.attributes.binary", "objectSID"); LdapContext ctx = new InitialLdapContext(env, null); return ctx; } public static boolean isDisabled(LdapContext ctx, String username, String baseDn) throws NamingException, IOException { boolean disabled = false; String filter = "sAMAccountName=" + username; SearchControls searchCtls = new SearchControls(); searchCtls.setSearchScope(SearchControls.SUBTREE_SCOPE); searchCtls.setCountLimit(1); searchCtls.setTimeLimit(0); // We want 500 results per request. ctx.setRequestControls(new Control[] { new PagedResultsControl(1, Control.CRITICAL) }); // We only want to retrieve the "distinguishedName" attribute. // You can specify other attributes/properties if you want here.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
