I use Ubuntu 12.04. I am already using Remmina both with RDP and VNC connections for several servers. For one of my servers I have a problem to login after login window opens. The server is Windows 2008 R2. The screen for entering user and password comes but does not accept the password. I guess the problem is with language but password does not contain any problematic letter except a $ sign. When connecting from Windows 7 there is no problem.
