Redmine

Hi matter how I would configure the svn command it does not work. Allways displays "Scm command not available. Please check settings on the administration panel." If I go to the admin panel I see the command I've put in but there is still red exclamation sign. Can you please provide some feedback how to solve this. I have already tried:
- upgrade of svn to version 1.6.x
- setting PATH in environment.rb
- change SVN_BIN in subversion_adapter.rb and adding stuff for certificates handling
- setting scm_subversion_command in configuration.yml
None of these works....
