The Connection.modify() methods let you add, replace,
and delete attributes values on an entry. Either the modifications are
expressed in LDIF, or you build a ModifyRequest to
express the changes.
The following excerpt demonstrates how to replace one attribute value and to add another.
final LDAPConnectionFactory factory = new LDAPConnectionFactory(host, port);
Connection connection = null;
try {
connection = factory.getConnection();
// Bind as a user who has the right to modify entries.
connection.bind(adminDN, adminPwd);
// Here, entry is a user entry with DN cn=Bob,ou=People,dc=example,dc=com.
Entry old = TreeMapEntry.deepCopyOfEntry(entry);
entry = entry.replaceAttribute("mail", "spammer@example.com")
.addAttribute("description", "I see the fnords.");
ModifyRequest request = Entries.diffEntries(old, entry);
connection.modify(request);
} catch (final ErrorResultException e) {
System.err.println(e.getMessage());
System.exit(e.getResult().getResultCode().intValue());
return;
} finally {
if (connection != null) {
connection.close();
}
}
