I want to active Ldap Login Module in apache karaf 3.0.3. 

My karaf-jaas-module.xml is ;

```
      .
      .        
      .   

    <jaas:config name="karaf" rank="2">
      <jaas:module className="org.apache.karaf.jaas.modules.ldap.LDAPLoginModule" flags="required">
        initialContextFactory=com.sun.jndi.ldap.LdapCtxFactory
        connection.username=admin
        connection.password=xxxxxxx
        connection.protocol=
        connection.url=ldap://activedirectory_host:389
        user.base.dn=cn=orcladmin,cn=users,dc=vmldapdevelop,dc=com
        user.filter=(sAMAccountName=%u)
        user.search.subtree=true
        role.base.dn=ou=Groups,ou=there,DC=local
        role.name.attribute=cn
        role.filter=(member=%nsdn)
        role.search.subtree=true
        authentication=simple
      </jaas:module>
    </jaas:config>

   .
   .
   .

```

And i wrote jaas:realm-list in karaf console and not seen LdapLoginModule. 

```
karaf@root()> jaas:realm-list
Index | Realm Name | Login Module Class Name

----------------------------------------------------------------------------
1     | karaf      | org.apache.karaf.jaas.modules.properties.PropertiesLoginModule
2     | karaf      | org.apache.karaf.jaas.modules.publickey.PublickeyLoginModule

```

How can i do this?
