[galaxy-dev] any working example of auth_conf.xml validating against openldap?

Hi, currently I am validating my users with openldap in apache. As in the new release of galaxy there is native support to validate againts ldap from galaxy I have upgraded to latest galaxy release and I am trying to configure auth_conf.xml but I cannot manage to get it working with my openldap. I see the provided example auth_conf.xml.sample is validating again active directory. Can anyone provide a working auth_conf.xml which is working with openldap so I can take it as reference? thanks in advance for any help. regards, Pablo.
