Spring LDAP using Java Configuration

Question

I was following the samples of Spring LDAP project and was trying to convert xml configuration to Java Configuration.

I am trying to do CRUD operations on the LDAP server.

I was able to figure out the following,

This is the xml configuration for the application, which I am hoping to convert into Java Config.

<context:property-placeholder location="classpath:/ldap.properties"
        system-properties-mode="OVERRIDE" />
    <context:annotation-config />

    <ldap:context-source id="contextSource" password="${sample.ldap.password}"
        url="${sample.ldap.url}" username="${sample.ldap.userDn}" base="${sample.ldap.base}" />

    <ldap:ldap-template id="ldapTemplate"
        context-source-ref="contextSource" />

    <!-- This will scan the org.springframework.ldap.samples.useradmin.domain 
        package for interfaces extending CrudRepository (in our case, LdapRepository), 
        automatically creating repository beans based on these interfaces. -->
    <ldap:repositories base-package="com.cazysystems.appstore.model" />

    <!-- This one will never be referenced directly, but the ldap:repositories 
        tag will make sure it will be 'wired in', because the GroupRepo interface 
        extends from an interface that GroupRepoImpl imlements. -->
    <bean class="com.cazysystems.appstore.model.impli.GroupRepoImpl" />

    <bean class="com.cazysystems.appstore.model.impli.DepartmentRepoImpl" />

    <bean class="com.cazysystems.appstore.service.UserService">
        <property name="directoryType" value="${sample.ldap.directory.type}" />
    </bean>

So I have the following classes that are supposed to do the migration,

@Configuration
@EnableLdapRepositories("com.cazysystems.appstore.model")
public class LdapConfiguration {

    @Autowired
    Environment env;

    @Bean
    public LdapContextSource contextSource() {
        LdapContextSource contextSource = new LdapContextSource();
        contextSource.setUrl(env.getRequiredProperty("sample.ldap.url"));
        contextSource.setBase(env.getRequiredProperty("sample.ldap.base"));
        contextSource.setUserDn(env.getRequiredProperty("sample.ldap.userDn"));
        contextSource.setPassword(env
                .getRequiredProperty("sample.ldap.password"));
        return contextSource;
    }

    @Bean
    public LdapTemplate ldapTemplate() {
        return new LdapTemplate(contextSource());
    }

}

and the

 @Configuration
public class AuthenticationConfiguration extends
        GlobalAuthenticationConfigurerAdapter {

    @Autowired
    Environment env;

    @Override
    public void init(AuthenticationManagerBuilder auth) throws Exception {

        auth.ldapAuthentication()
                // .userDetailsContextMapper(userDetailsContextMapper())
                .userDnPatterns(
                        env.getRequiredProperty("ldap.user_dn_patterns"))
                .groupSearchBase(
                        env.getRequiredProperty("ldap.group_search_base"))
                .contextSource().ldif("classpath:setup_data.ldif")
                .url(env.getRequiredProperty("sample.ldap.url"))
                .managerDn("sample.ldap.userDn")
                .managerPassword("sample.ldap.password").port(10389);
    }

}

But when I run the application,

I get the following error,

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'groupRepo': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Not an managed type: class com.cazysystems.appstore.model.Group

But under the com.cazysystems.appstore.modelpackage,

I have,

public interface GroupRepo extends LdapRepository<Group>, GroupRepoExtension {
    public final static String USER_GROUP = "ROLE_USER";

    Group findByName(String groupName);

    @Query("(member={0})")
    Collection<Group> findByMember(Name member);
}

and

@Entry(objectClasses = { "groupOfNames", "top" }, base = "ou=Groups")
public final class Group {
    @Id
    private Name id;

    @Attribute(name = "cn")
    @DnAttribute(value = "cn", index = 1)
    private String name;

    @Attribute(name = "description")
    private String description;

    @Attribute(name = "member")
    private Set<Name> members = new HashSet<Name>();

    public String getDescription() {
        return description;
    }

    public void setDescription(String description) {
        this.description = description;
    }

    public Set<Name> getMembers() {
        return members;
    }

    public void addMember(Name newMember) {
        members.add(newMember);
    }

    public void removeMember(Name member) {
        members.remove(member);
    }

    public Name getId() {
        return id;
    }

    public void setId(Name id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

But this annotation is supposed to do the trick, But it is not working,

@EnableLdapRepositories("com.cazysystems.appstore.model")

I am using the following dependencies in my pom.

<dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-ldap</artifactId>
    </dependency>


    <dependency>
        <groupId>org.springframework.ldap</groupId>
        <artifactId>spring-ldap-core</artifactId>
        <version>2.0.3.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.ldap</groupId>
        <artifactId>spring-ldap-core-tiger</artifactId>
        <version>2.0.3.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>org.springframework.data</groupId>
        <artifactId>spring-data-commons</artifactId>
    </dependency>

I am not sure what I am doing wrong, because the documentation on this are very hard to find. Please help if you know this stuff.

EDIT:

Here is my Controller class,

@Controller
public class GroupController {

    @Autowired
    private GroupRepo groupRepo;

    @Autowired
    private UserService userService;

    @RequestMapping(value = "/groups", method = GET)
    public String listGroups(ModelMap map) {
        map.put("groups", groupRepo.getAllGroupNames());
        return "listGroups";
    }

    @RequestMapping(value = "/newGroup", method = GET)
    public String initNewGroup() {
        return "newGroup";
    }

    @RequestMapping(value = "/groups", method = POST)

        map.put("group", foundGroup);

        final Set<User> groupMembers = userService.findAllMembers(foundGroup.getMembers());
        map.put("members", groupMembers);

        Iterable<User> otherUsers = Iterables.filter(userService.findAll(), new Predicate<User>() {
            @Override
            public boolean apply(User user) {
                return !groupMembers.contains(user);
            }
        });
        map.put("nonMembers", Lists.newLinkedList(otherUsers));

        return "editGroup";
    }

    @RequestMapping(value = "/groups/{name}/members", method = POST)
    public String addUserToGroup(@PathVariable String name, @RequestParam String userId) {
        Group group = groupRepo.findByName(name);
        group.addMember(userService.toAbsoluteDn(LdapUtils.newLdapName(userId)));

        groupRepo.save(group);

        return "redirect:/groups/" + name;
    }

    @RequestMapping(value = "/groups/{name}/members", method = DELETE)
    public String removeUserFromGroup(@PathVariable String name, @RequestParam String userId) {
        Group group = groupRepo.findByName(name);
        group.removeMember(userService.toAbsoluteDn(LdapUtils.newLdapName(userId)));

        groupRepo.save(group);

        return "redirect:/groups/" + name;
    }
}

During the trouble shooting,

I noticed that, the application fails only when I used both JPA and LDAP together. When I removed all the JPA dependencies and implementations, the application works as expected.

The issue seems to be caused by the conflict between JPA and LDAP dependencies. But I am not sure how to resolve it.

You are not stating what you want to achive, create a user, read user, seems to me you are mixing stuff from spring-data with ldap. Ill paste my configuration maybe it helps, if it does i can show you how im adding users with this configurations, again im not sure what you want to achieve, hope it helps

@Configuration
public class LdapManagerConfiguration {

@Autowired
Environment ldapProperties;

@Bean
public LdapContextSource contextSourceTarget() {
    LdapContextSource ldapContextSource = new LdapContextSource();
    ldapContextSource.setUrl(ldapProperties.getProperty("auth.ldap.url"));
    ldapContextSource.setBase(ldapProperties.getProperty("auth.ldap.base"));
    ldapContextSource.setUserDn(ldapProperties
            .getProperty("auth.ldap.userdn"));
    ldapContextSource.setPassword(ldapProperties
            .getProperty("auth.ldap.password"));

    return ldapContextSource;

}

@Bean
public LdapTemplate ldapTemplate() {

    return new LdapTemplate(contextSourceTarget());

}

@Bean
public InetOrgPersonContextMapper inetOrgPersonContextMapper() {
    return new InetOrgPersonContextMapper();
}

@Bean
public DefaultLdapUsernameToDnMapper defaultLdapUsernameToDnMapper() {
    return new DefaultLdapUsernameToDnMapper(
            ldapProperties.getProperty("auth.ldap.groupbase"),
            ldapProperties.getProperty("auth.ldap.attributename.username"));// "uid"
}

@Bean
public LdapUserDetailsManager ldapUserDetailManager() {
    LdapUserDetailsManager userManager = new LdapUserDetailsManager(
            contextSourceTarget());

    userManager.setGroupSearchBase(ldapProperties
            .getProperty("auth.ldap.groupbase"));
    userManager.setUserDetailsMapper(inetOrgPersonContextMapper());
    userManager.setUsernameMapper(defaultLdapUsernameToDnMapper());
    userManager.setGroupRoleAttributeName(ldapProperties
            .getProperty("auth.ldap.attributename.grouprole"));
    userManager.setGroupMemberAttributeName(ldapProperties
            .getProperty("auth.ldap.attributename.groupmemeber"));

    return userManager;

}

}

to add a user then

Logger logger = LoggerFactory.getLogger(LdapUserManagerImpl.class);

@Autowired
LdapTemplate ldapTemplate;

@Autowired
Environment ldapProperties;

final String passwordAttribute = "userPassword";

@Override
public boolean createUser(final String user,
        final String defaultPasswordPolicy)
        throws UserAlreadyExistsAsInactive {

    boolean created = false;

    String inactivePeople = ldapProperties.getProperty(
            "auth.ldap.inactive.groupbase").replace("ou=", "");

    String activePeople = ldapProperties.getProperty("auth.ldap.groupbase")
            .replace("ou=", "");

    if (existsUser(user, inactivePeople)) {
        logger.error("User " + user
                + " already exists in ldap but it's incative");
        throw new UserAlreadyExistsAsInactive(user);

    }
    if (existsUser(user, activePeople)) {
        logger.error("User " + user
                + " already exists in ldap and is Active");
        return false;
    }

    try {

        ldapTemplate.bind(buildDn(user, inactivePeople), null,
                createUserDetails(user, defaultPasswordPolicy));
        created = true;

    } catch (Exception e) {
        logger.error(
                "Unexpected exception when trying to create user in LdapException",
                e);
        return created;
    }
    return created;
}

So That Will Be the create

This would be de read

public UserI findUser(String userName, String group) {

    try {
        String dn = buildDN(userName, group);
        User user = ldapTemplate.lookup(dn, new UserAttributesMapper());
        return user;
    } catch (NameNotFoundException e) {
        return new UserNullObject();
    }

}

This the update

@Override
public void changeUserGroup(String userName, String oldGroup,
        String newGroup) throws ReLocoException {

    UserI user = findUser(userName, oldGroup);
    if (!user.isEmpty()) {

        try {

            Object password = getLdapPassword(userName, oldGroup);

            ldapTemplate.unbind(buildDN(userName, oldGroup));

            String defaultPasswordPolicy = ldapProperties
                    .getProperty("auth.ldap.default.userpollicy");

            ldapTemplate.bind(buildDN(userName, newGroup), null,
                    createUserDetails(userName, defaultPasswordPolicy));

            applyPasswordToUser(userName, password, newGroup);

        } catch (Exception e) {
            logger.error("Error on change user from incative to active people group "
                    + e);
            throw new ConfirmAccountValidationCodeException(userName);
        }
    } else {

        throw new UserNotFoundException(
                "The username provided for the given group '" + oldGroup
                        + "' does not exist");
    }

}

Do you have your application annotated with @SpringBootApplication or @EnableAutoConfiguration? If so, the automatic @Repository and @Entity scanning may be wrongly identifying your LDAP repository as a JPA repository, hence the error. Try excluding the automatic configuration for JPA Repositories from your application's automatic configuration: @SpringBootApplication(exclude={JpaRepositoriesAutoConfiguration.class})
