ABR 11 and Ubutnu Agent Installation

Hello there,

I just installed ABR 11 went through the initial configuration. I am able to install the agent by downloading linux agent but I don't see the options either in agent or in ABR mgmt console to add my Ubuntu machine. When I try adding from the ABR console, I get a generic login failure (see below). I have already looked at other threads that talk about this message and per one of them, it was supposed to have fixed in the latest release. I would really appreciate it someone could let me know if it's possible to manage Ubuntu servers via AMS.

Thanks
