Erm... Do you have or can you get a local connection? from what I am guessing has just happened, you nuked the login system itself... also how far does SSH get? is it just certain accounts you can not login as, or all of them? (does it request login info or fail to get that far?)
the fix would likely be "yum install nss" you might need to use single user mode if the local connection also will not allow logins but I am not so sure, from what I can see of nss it's related to the login system.
