/bin/login: Permission denied

[Ramnath Muthukumar <ramuatavon yahoo co in>]

hi guys

i ve a red hat linux 7 version
iam facing a problem while login in to my system

i am getting the login prompt to enter 
uesr id :

entering the userid and pressing enter refreshes back to the 

user id : 

login prompt

so i tried restarting my system in single user mode

i ve seen the /bin/login script 

its file size was 0 bytes and the permition was
644
i copied the /bin/login script from another m/h and tried replacing my
login script but... i couldnt able to do

i then tried changing the permision to 755 like this

chmod 755 /bin/login (in single user mode with super user permission)
but is gave a message

permission denied

i tried removing to remove the /bin/login script as
rm -f /bin/login 
but it gave a message like

rm: cannot unlink 'login' : Operation not permitted

i am totally helpless 

please give me a solution for this..

regards
ramnath muthukumar
