My security-application-context.xml:

<beans:bean id="contextSource"
            class="org.springframework.security.ldap.DefaultSpringSecurityContextSource">
      <beans:constructor-arg value="ldap://127.0.0.1:7001/DC=base_domain"/>
      <beans:property name="userDn" value="CN=Admin"/>
      <beans:property name="password" value="weblogic"/>
    </beans:bean>

    <beans:bean id="ldapAuthProvider"
        class="org.springframework.security.ldap.authentication.LdapAuthenticationProvider">
      <beans:constructor-arg>
       <beans:bean class="org.springframework.security.ldap.authentication.BindAuthenticator">

         <beans:property name="userDnPatterns">
           <beans:list><beans:value>uid={0},ou=people</beans:value></beans:list>

     </beans:constructor-arg>
    </beans:bean>
<authentication-manager>
        <ldap-authentication-provider server-ref="ldapAuthProvider" />
    </authentication-manager>

<spring.security.version>3.0.0.RELEASE</spring.version>

ANY help will be apreciated,

Ths a Lot!!!

<ldap-authentication-provider> configures LdapAuthenticationProvider itself, so you don't need ldapAuthProvider as a separate bean.

So, you should use either <ldap-authentication-provider> as descibed in the docs:

 <ldap-authentication-provider user-dn-pattern="uid={0},ou=people" ... />

Or use a provider created manually as a separate bean using <authentication-provider>:

 <authentication-provider ref = "ldapAuthProvider" />.
