Resolution
Ensure that the Realm specified in your Subversion repository configuration includes the server, port, and the SvnRealmName. The correct syntax for the Realm is proto://server:port SvnRealmName.
You can find out the SVN Realm name on your client like this:
svn --no-auth-cache --config-dir invalid info proto://host:port/path/to/repo The SVN realm name is set in your SVN Server config svnserve.conf (realm = realm-name).
