Some missing documentation identified by user trying to configure the MDS
execution aggregator that is part of the RLS.

---------------------------

    Silvu,

    It looks like the script was registered correctly with MDS4 – as far as I
can tell. The problem is that the RLS is running with authentication and the
script (invoked by MDS) does not have a security context. I believe you can fix
this one of two ways:

    1.       Set the env for X509_USER_CERT and X509_USER_KEY to the
container’s cert/key
    2.       Modify the script such that it sets them

    Then, make sure the container cert’s DN is in the gridmap file on the
machine that the RLS is running on.

    I think that would resolve the issue.

    The RLS provides a script for use with MDS:

    And then you can see instructions from MDS on how to use such scripts:

    Hi,
    I've tried to register rls to MDS4.
    When I query the index I receive the following error:

    I'm not sure that the defaultRegistrantEPR should be set this way but I
don't know how to set it.
    Please help.
