[Exist-open] Secure user login using xmldb api?

[Darren G. <da...@on...>]

Hi,
   I couldn't find it in the docs (sorry if I missed it!), but I was 
wanting to know how to login a user with their password from xmldb API 
in Java? I have a URI to the database such as 
xmldb:exist://localhost:8080/exist/xmlrpc

Where, how do I specify the user/password credentials?

thank you!
Darren
