Right now we are working on the patch for the "Cannot get effective rights from ACL" problem. Could you please try to setup the special development build and tell us whether the problem is solved or not?
You can download the special built at: http://www.visualsvn.com/files/beta/VisualSVN-Server-2.0.3.20456.msi Thanks in advance! -- With best regards, Danil Shopyrin VisualSVN Team
