Spring Testing an Ldap Module Using a Custom Schema

Question

I am trying to install the built-in ldap for unit test using Spring Ldap. But I need to use a custom schema for custom objectClasses / attributes definitions. How to configure it using Spring Ldap test ( LdapTestUtils ?)

Actually, if I run the test, it does not mean that my own objectClass "myOb" is not defined in the circuit with the following message:

org.springframework.ldap.UncategorizedLdapException: Failed to populate LDIF; nested exception is javax.naming.directory.NoSuchAttributeException: [LDAP: error code 16 - NO_SUCH_ATTRIBUTE: failed for Add Request : ... : OID for name 'myOb' was not found within the OID registry]; remaining name 'cn=123456, ou=MyUser, o=company.com' 

If I comment on objectClass: myOb from ldif, the test fails with a null value (the attribute is not readable).

Here is my test class:

 @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(classes = LdapConfiguration.class, loader = AnnotationConfigContextLoader.class) public class LdapTest { // Ldap port private static final int LDAP_PORT = 18880; // Base DN for test data private static final LdapName baseName = LdapUtils.newLdapName("o=company.com"); @Autowired LdapTemplate ldapTemplate; @BeforeClass public static void setupBeforeClass() { LdapTestUtils.startEmbeddedServer(LDAP_PORT, baseName.toString(), "ldaptest"); // How to load schema definition ? } @AfterClass public static void teardownAfterClass() throws Exception { LdapTestUtils.shutdownEmbeddedServer(); } @Before public void setup() throws Exception { LdapTestUtils.cleanAndSetup(ldapTemplate.getContextSource(), baseName, new ClassPathResource("ldap/test-users.ldif")); } @Test public void testSearchLdap() throws Exception { String myObId = ldapTemplate.lookup(LdapNameBuilder.newInstance("ou=MyUser, o=company.com").add("cn", "123456").build(), new AbstractContextMapper<String>() { @Override protected String doMapFromContext(DirContextOperations ctx) { return ctx.getStringAttribute("myObId"); // custom type } }); Assert.assertNotNull(myObId); // myObId is null if I comment `objectClass: myOb` ! } } 

and my ldif:

 dn: ou=MyUser, o=company.com ou: User description: MyUser objectClass: top objectClass: organizationalunit dn: cn=123456, ou=MyUser, o=company.com objectClass: top objectClass: person objectClass: myOb cn: 123456 sn: 823456 myObId: TEST

I don't know how to do this with Spring Ldap ... But I use Unboundid InMemoryDirectoryServer in my unit tests. This server implementation does not limit any user-defined objectClasses / attributes definitions. If you want, I can share my JUnitRule here. The rule starts the InMemory server and loads ldiff into it.

UPDATED:

 public class LdapServerRule extends ExternalResource { private static final Log LOG = LogFactory .getLog(LdapServerRule.class); public static final String DefaultDn = "cn=Directory Manager"; public static final String DefaultPassword = "password"; private String baseDn; private String dn; private String password; private String lDiffPath; private InMemoryDirectoryServer server; private int listenPort; public LdapServerRule(String baseDn, String lDiffPath) { this(baseDn, lDiffPath, 0); } public LdapServerRule(String baseDn, String lDiffPath, int listenPort) { this.lDiffPath = lDiffPath; this.baseDn = baseDn; this.dn = DefaultDn; this.password = DefaultPassword; this.listenPort = listenPort; } @Override protected void before() { start(); } @Override protected void after() { stop(); } public int getRunningPort() { return getServer().getListenPort(); } private void start() { InMemoryDirectoryServerConfig config; try { LOG.info("LDAP server " + toString() + " starting..."); config = new InMemoryDirectoryServerConfig(getBaseDn()); config.addAdditionalBindCredentials(getDn(), getPassword()); config.setSchema(null); config.setListenerConfigs( InMemoryListenerConfig.createLDAPConfig("LDAP", getListenPort())); setServer(new InMemoryDirectoryServer(config)); getServer().importFromLDIF(true, getLDiffPath()); getServer().startListening(); LOG.info("LDAP server " + toString() + " started. Listen on port " + getServer().getListenPort()); } catch (Exception e) { throw new RuntimeException(e); } } private void stop() { server.shutDown(true); LOG.info("LDAP server " + toString() + " stopped"); } public String getBaseDn() { return baseDn; } public String getDn() { return dn; } public String getPassword() { return password; } public InMemoryDirectoryServer getServer() { return server; } public void setServer(InMemoryDirectoryServer server) { this.server = server; } public String getLDiffPath() { return lDiffPath; } public int getListenPort() { return listenPort; } @Override public String toString() { return com.google.common.base.Objects.toStringHelper(this) .add("baseDn", baseDn) .add("listenPort", listenPort) .toString(); } 

}

You can use this rule as follows

 @ClassRule public static final LdapServerRule LDAP_RULE = new LdapServerRule("dc=mmkauth", resourceFilePath("data.ldiff")); 

LDAP_RULE.getListenPort () returns the actual port to connect to or you can pass the port directly to the constructor
