Spring Security LDAP - login problem (ProviderNotFoundException) - spring

Question

I have problem with LDAP Spring Security, I'm trying to authorise against the LDAP server. I have the spring configuration xml file (security-config.xml) like this:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:sec="http://www.springframework.org/schema/security"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd
http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-2.0.4.xsd">
<bean id="contextSource" class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
<constructor-arg value="ldap://111.111.111.111"/>
<property name="userDn" value="cn=auth-user,ou=System,dc=foo,dc=com"/>
<property name="password" value="fooPwd"/>
</bean>
<bean id="ldapAuthProvider" class="org.springframework.security.providers.ldap.LdapAuthenticationProvider">
<constructor-arg>
<bean class="org.springframework.security.providers.ldap.authenticator.BindAuthenticator">
<constructor-arg ref="contextSource"/>
<property name="userSearch">
<bean id="userSearch" class="org.springframework.security.ldap.search.FilterBasedLdapUserSearch">
<constructor-arg index="0" value="ou=people"/>
<constructor-arg index="1" value="(uid={0})"/>
<constructor-arg index="2" ref="contextSource" />
</bean>
</property>
</bean>
</constructor-arg>
<constructor-arg>
<bean class="com.company.name.services.UserAuthoritiesPopulator" />
</constructor-arg>
</bean>
</beans>
In the login controller (LoginController.java) I'm authorising like this:
#RequestMapping(value = "/login", method = RequestMethod.POST)
public String loginPPost(String username, String password, Model model, HttpServletRequest req, HttpServletResponse res) throws SQLException {
UsernamePasswordAuthenticationToken authRequest = new UsernamePasswordAuthenticationToken(username, password);
Authentication authentication = authenticationManager.authenticate(authRequest);
SecurityContextHolder.getContext().setAuthentication(authentication);
...
}
The method "authenticationManager.authenticate(authRequest)" throws this exception:
org.springframework.security.providers.ProviderNotFoundException: No AuthenticationProvider found for org.springframework.security.providers.UsernamePasswordAuthenticationToken
at org.springframework.security.providers.ProviderManager.doAuthentication(ProviderManager.java:214)
at org.springframework.security.AbstractAuthenticationManager.authenticate(AbstractAuthenticationManager.java:46)
Does anybody know how to solve this problem? Should I use different method for authorisation? Or is my configuration bad?
Thanks for any help,
Mateo

You must add the tag 'sec:custom-authentication-provider' in your authentication provider bean:
<bean id="ldapAuthProvider" class="org.springframework.security.providers.ldap.LdapAuthenticationProvider">
<sec:custom-authentication-provider/>
...
</bean>
You can find an example that use Crowd instead of LDAP on my blog:
