Cannot use Spring LDAP with Spring Security

Question

I want to authenticate users against our AD so I understand that I need spring security and spring ldap.

Here is what is in my POM:

<groupId>org.springframework.security</groupId>
<artifactId>org.springframework.security.core</artifactId>
<version>3.0.0.RELEASE</version>
</dependency>
...
<dependency>
    <groupId>org.springframework.ldap</groupId>
    <artifactId>spring-ldap</artifactId>
    <version>1.3.0.RELEASE</version>
    <type>pom</type>
    <scope>provided</scope>
</dependency>

Here are the respective entries from my secruity-context:

<ldap-authentication-provider user-dn-pattern="CN=0},OU=CAN,OU=NOT,OU=TELL,OU=YOU"/>
    ..  
<!-- LDAP Security Configuration -->
<ldap-server url="ldap://10.9.1.1:389/DC=TELL,DC=YOU"/>

However when I run my application using:

mvn jetty:run

I get following error:

If you are using LDAP with Spring Security, please ensure that you include the spring-ldap jar file in your application; nested exception is java.lang.ClassNotFoundException: org.springframework.ldap.core.support.BaseLdapPathContextSource:

Answer 1

A dependency of type pom won't provide any classes. Use this dependency instead:

<dependency>
  <groupId>org.springframework.ldap</groupId>
  <artifactId>spring-ldap-core</artifactId>
  <version>1.3.0.RELEASE</version>
</dependency>

This artifact contains the o.s.l.c.s.BaseLdapPathContextSource class which is currently missing.
