Ever since build 5368, including the latested 6.0 beta, I have not been able to authenticate with our SVN repository. I keep getting the credentials dialog.
As an experiment I copied the plugins\svn4idea\ from the 5368 install over the top of the plugin in the 6.0 beta and now the SVN authentication (and checkout, so far) seems to work OK in the 6.0 beta.
So it seems that there's been some recent change to the svn4idea plugin that is broken?
I'm connecting to a version 1.3.1 repository hosted under Apache on Windows. Apache is using NTLM authentication with default domain (ie. user name is "joebloggs" not "DOMAIN\joebloggs").
