            if (enm.hasMore()) {
                SearchResult result = (SearchResult) enm.next();
                dn = result.getNameInNamespace();

                System.out.println("dn: "+dn);
            }

            if (dn == null || enm.hasMore()) {
                // uid not found or not unique
                throw new NamingException("Authentication failed");
            }

            // Step 3: Bind with found DN and given password
            ctx.addToEnvironment(Context.SECURITY_PRINCIPAL, dn);
            ctx.addToEnvironment(Context.SECURITY_CREDENTIALS, password);
            // Perform a lookup in order to force a bind operation with JNDI
            ctx.lookup(dn);
            System.out.println("Authentication successful");

        } catch (NamingException e) {
            System.out.println(e.getMessage());
        } finally {
            ctx.close();
        }
    }
}

The above program will authenticate a user as well as it will show the dn for the user. And here I am using Apache ds in eclipse. From the above program I am trying to get the dn: for user1 who's base is ou=users,ou=system but I am not getting the dn: for user1.

假设 user1 的 DN 是“uid=user1,ou=users,ou=system”，那么您的过滤器应该更改为“(uid=user1)”。另请注意，您请求的属性应该是错误的 - new String[] { "uid" }
