When I enter the url for the server into a browser (Chrome, Firefox) I can access the repository if I accept the security exception.
When I enter the url into svn repository location in eclipse, along with the user name and password, I get an error occured while accessing the repository entry.
The error from eclipse is SVN: 0x00400006: Validate Repository Location operation finished with error: Selected SVN connector library is not available or cannot be loaded.
The instructions from this site worked
http://www.polarion.com/products/svn/subversive/download.php
In eclipse, go to help/install new software
Add the site
http://community.polarion.com/projects/subversive/download/eclipse/3.0/juno-site/
Install the svn connectors and svnkit.
Now, I can reach the server repository from eclipse. It may be helpful to use New / project from repository.
