Unable to login to my drobo knowing username and password 810n

I joined my drobo to the AD. When I try to access my shares or any other tool I have to login but but but the login isnt working. Tried user names with admin priviledges from my domain and nothing. I tried the user name and password I setup in the Administrator section and nothing. Actually when I tried to do the last one my user name appears on the top and automatically logs me out. soooooooooo
