I have an access to a machine on lan via ssh and I use key based authentication.I created one more account on the remote machine and copied
cp home/oldaccount/.ssh/authorized_keys home/newaccount/.ssh/authorized_keys
Now when I tried to login to the other account via ssh from my laptop it did not worked.Though the copy of keys from laptop .ssh/id_rsa.pub to
remote machine new account .ssh/authorized keys did worked.
I was wondering I had added same keys to old account so why did simple copying the authorized keys from one account to another did not worked.
Because when I did cat id_rsa.pub > authorized_keys in new account I had created same file which was in old account.
Why is this happening or my observation is wrong.
