What do you want to know? Feel free to ask we will provide you 
information or pointers to information.

ok

ok. This if for RRD MA user in eXist.

ok

This may look strange but it was required because there was an 
inconsistency when the user installed the service but eXist was already 
installed before and the admin password wan not empty. Beceause WebAdmin 
had no way to get the current admin password of eXist, the user needs to 
input it. If the user wishes to keep the old password he just retypes 
the old password in "eXist admin's password" field.

This is only an example metadata configuration file which comes with the 
service by default. It contains some test data to allow you verifying 
your service. In real environment you must create your own config file 
based on this template and the guide.
While initializing RD MA this XML file will be copied from this location 
to the eXist database

I will leave AuthN questions for Candido.

Can you maybe tell me where did you see the main difficulty here? This 
is described in the MDM guide but we could of course improve it.

Thank you and regards,
