Servidor recusando chave pública com PuTTY

Question

Estou configurando nosso novo servidor RHEL 7 e estou realmente empenhado em tentar que ele aceite meu par de chaves privado / público.

Tudo parece bastante semelhante em comparação com a configuração do sshd do servidor antigo.

Atual sshd_config :

Port 22
Protocol 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key
KeyRegenerationInterval 3600
ServerKeyBits 1024
SyslogFacility AUTHPRIV
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile   .ssh/authorized_keys
PasswordAuthentication yes
ChallengeResponseAuthentication no
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
UsePAM yes
X11Forwarding yes
UsePrivilegeSeparation sandbox
AcceptEnv LANG LC_CTYPE LC_NUMERIC LC_TIME LC_COLLATE LC_MONETARY LC_MESSAGES
AcceptEnv LC_PAPER LC_NAME LC_ADDRESS LC_TELEPHONE LC_MEASUREMENT
AcceptEnv LC_IDENTIFICATION LC_ALL LANGUAGE
AcceptEnv XMODIFIERS
Subsystem   sftp  /usr/libexec/openssh/sftp-server

Efetuando login usando o PuTTY, recebo:

Using username "jweinraub".
Server refused our key

Minhas permissões são

drwx------. jweinraub jweinraub unconfined_u:object_r:ssh_home_t:s0 .ssh/
-rw-------. jweinraub jweinraub unconfined_u:object_r:ssh_home_t:s0 authorized_keys

E com depuração 3
