HOWTO configure MDM login window?

[dexl]

Please help me configure the login window of MDM manager. I cannot find any usable information online about it. I have already chosen "plain style with face browser" and changed the background photo. What I don't know is:
- how do I change the icon for individual users, I don't like the ugly generic one.
- how do I enable automatic login of one of the users so that it WORKS. I have enabled it under security tab and chose the user, but it doesn't work!

I'd like to get some proof why MDM is the best login manager. Where are the things mentioned in this quote: "graphical configuration tools, themeability, remote, automatic and timed login, event scripting, language selection and it comes with more features than any other Display Manager currently available"??? for I am not able to change very basic things in it...

Thanks!

Is there any tutorial online that I could follow? I have also tried searching this forum, but haven't found anything.
