I am not able to create user in RHEl 5. I have deleted the user ram using the command userdel -d ram.
It had deleted the directory of ram as well. But today when I tried to create the user ram again, it gives me a message user ram already exists.

I have checked cat /etc/passwd | grep ram
and cat /etc/shadow | grep ram.

I didn't get any entery of ram in these two files.

Please let me know the steps so that I will be able to create the user ram again.
