While comparing the size of /bin/login with the another server, I found the size of 
the file /bin/login more. When I replaced this login file, from another server then it 
worked i.e. I could login as regular. But, when I rebooted the server, the problem 
was again. The size of the login file is automatically changed and the problem again 
recurred.
