[SLE] who logged in?

Hi, Is there a command that will tell me who logged in into my system in the last 24 hours (or, last n days, say)? Or, is there a command that tells me when each user last logged in? I did my "homework," but couldn't find such a command in my books. I looked into /var/log/messages, but that's cumbersome.
