Unable to use Spring LDAP with Spring Security

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 relevant 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 launch my application using:

 mvn jetty:run

I get the 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: java.lang.ClassNotFoundException: org.springframework.ldap.core.support.BaseLdapPathContextSource at java.net.URLClassLoader$1.run(URLClassLoader.java:200) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:188) at java.lang.ClassLoader.loadClass(ClassLoader.java:307) at org.codehaus.classworlds.RealmClassLoader.loadClassDirect(RealmClassLoader.java:195) at org.codehaus.classworlds.DefaultClassRealm.loadClass(DefaultClassRealm.java:255) at org.codehaus.classworlds.DefaultClassRealm.loadClass(DefaultClassRealm.java:274) at org.codehaus.classworlds.RealmClassLoader.loadClass(RealmClassLoader.java:214) at java.lang.ClassLoader.loadClass(ClassLoader.java:252) at org.mortbay.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:375) at org.mortbay.jetty.webapp.WebAppClassLoader.loadClass(WebAppClassLoader.java:337) at org.springframework.util.ClassUtils.forName(ClassUtils.java:258) at org.springframework.security.config.ldap.ContextSourceSettingPostProcessor.postProcessBeanFactory(ContextSourceSettingPostProcessor.java:33)

A pom type dependency does not 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 oslcsBaseLdapPathContextSource class, which is currently missing.

Just for the sake of completeness. Here is a list of dependencies that works for me:

  <dependency> <groupId>org.springframework.security</groupId> <artifactId>org.springframework.security.core</artifactId> <version>3.0.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>org.springframework.security.config</artifactId> <version>3.0.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>org.springframework.security.web</artifactId> <version>3.0.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>org.springframework.security.taglibs</artifactId> <version>3.0.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.ldap</groupId> <artifactId>spring-ldap-core</artifactId> <version>1.3.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.ldap</groupId> <artifactId>spring-ldap-core-tiger</artifactId> <version>1.3.0.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-ldap</artifactId> <version>3.0.1.RELEASE</version> </dependency>

<type>pom</type> looks suspicious to me. Try changing the type to jar
