I tried to setup the Redmine Applicance and let me say that the LDAP Auth "just worked"
While trying to setup the Subversion repository though, it didn't work. I searched the forums but people had reported problems only as back as 2009 (Redmine + SVN).
I tried the "automatic WS" option as well, but that didn't work either.
* Would it possible to clarify in the UI itself what the URL exactly means (i.e. where the directory would get created for the different protocols).
