CentOS7 SFTP - не обнаружение закрытого ключа

У меня есть сервер CentOS 7 с OpenSSH, установленным, который это - основная цель, должен быть сервер SFTP. У меня есть несколько клиентов, которые соединяются с этим сервером с помощью или Частной/С открытым ключом аутентификации или Паролей, и они все соединяются прекрасный.

У меня есть один конкретный клиент, который соединяется с нашим сервером с помощью GlobalScape EFT 5.1 с комбинацией Пароля и Частный/С открытым ключом.

Открытый ключ они предоставили нам запуски с комментарием ниже и по нескольким строкам.

---- BEGIN SSH2 PUBLIC KEY ----

Я преобразовал открытый ключ с помощью SSH-KEYGEN-i-f и поместил его в authorized_keys файле. Это находится теперь на одной строке и запускается с ssh-rsa.

При рассмотрении журналов (который я вставил ниже) это, кажется, не распознает, что они используют ключ.

Я должен добавить, что мы недавно обновили сервер от CentOS6 до 7, и соединение раньше работало над CentOS6. Насколько я могу сказать, что конфигурация идентична.

Ниже текущий sshd_config файл, который мы используем.

#   $OpenBSD: sshd_config,v 1.80 2008/07/02 02:24:18 djm Exp $

# This is the sshd server system-wide configuration file.  See
# sshd_config(5) for more information.

# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin

# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented.  Uncommented options change a
# default value.

#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

# Disable legacy (protocol version 1) support in the server for new
# installations. In future the default will change to require explicit
# activation of protocol 1

# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key

# Set this to 'yes' to enable PAM authentication, account processing, 
# and session processing. If this is enabled, PAM authentication will 
# be allowed through the ChallengeResponseAuthentication and
# PasswordAuthentication.  Depending on your PAM configuration,
# PAM authentication via ChallengeResponseAuthentication may bypass
