Howto use ReadOnlyUsersLDAPRepository

[Lanfeust troy]

Hi all

I'm trying Apache James Server and I don't understand how can i use
ReadOnlyUsersLDAPRepository.

I have the following in usersrepository.xml

<usersrepository>
    <!-- Read-Only LDAP based UsersRepository -->
    <repository name="LocalUsers"
class="org.apache.james.user.ldap.ReadOnlyUsersLDAPRepository"
ldapHost="ldap://obm3.kvm.rla:389";
        principal="" credentials="" userBase="dc=local"
userIdAttribute="mailBox"/>;
<!--
  <repository name="LocalUsers"
class="org.apache.james.user.jpa.JPAUsersRepository">
      <algorithm>MD5</algorithm>
  </repository>
-->
</usersrepository>

but the server don't want to start with this error:

Error creating bean with name 'usersstore'
Error creating bean with name 'localusersrepository':


in spring-beans.xml

<bean id="usersstore" class="org.apache.james.user.lib.JamesUsersStore" >
   <property name="defaultRepository" value="LocalUsers"/>
</bean>

<bean id="localusersrepository"
class="org.apache.james.user.lib.LocalUsersRepository"

thanks for help
