Hi When i create username like this "useradd user.name" It shows the error message saying that the name contains invalid characters Is there any way to create username like that, When i edit the /etc/useradd, /etc/shadow, /etc/group and /etc/gshadow it worked fine for me -- Thanks and Regards ------------------------------ N S Vikram, Asso.
