Putty + Server refused our key

[longhair]

I keep getting the error "Server refused our key" when I try to log in using Putty.

Here is what I have done:

1) Created a new user, logged out and logged in with new user.
2) Created a directory ~/.ssh
3) chmod 700 ~/.ssh
4) ssh-keygen -t rsa -b 4096
5) cat id_rsa.pub >> authorized_keys
6) chmod 600 ~/.ssh/authorized_keys
7) /etc/ssh/sshd_config:

PermitRootLogin no

RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile
%u/.ssh/authorized_keys

8) sudo service ssh restart
9) Transfered id_rsa to Windows, converted it to .ppk file to be used with Putty.
10) rm ida_rsa and id_rsa.pub
11) exit
12) Log back in only to see Server refused our key.

cat /var/log/auth.log

I couldn't find an answer after searching google for a couple of hours

Have you seen this article?

That article was where I got the idea to look at the /var/log/auth.log file.

I just tried to make a new key pair (probably the 10th try today) and still being refused.

May be this will help?

Sounds like the problem is the new user not being allowed to use SSH.

The new user is able to use SSH or else it would not allow a log in at all.

I made a Debian 7 VM with only SSH Server and Standard system utilities. After that I followed the same steps from my original post.

On the first try, the SSH keys worked. Does Proxmox have another public key somewhere that is causing the issues?

Hi,
no - work for me without trouble.

Are you sure, that you don't have linebreaks in the public key?!

This is strange indeed. I ended up doing a fresh install, created a new user without sudo or anything extra and now it works.

I don't know what caused the issues from the previous install...
