So you didn't read the user's manual?

Do you mean ~/.ssh aka $HOME/.ssh?  /.ssh doesn't have a meaning for
users.

Which won't work.  sshd relies on the information given in /etc/passwd.
mkpasswd -d is your friend!

This is really bad.  sshd refuses files with write permissions for
others for security reasons.  Also make sure the user's home dir as well
as ~/.ssh have strict permissions and don't allow writing to group and
others.
