opensshd/openssh - 키 쌍 또는 비밀번호 허용

사용자가 키 쌍을 사용하여 인증한 다음 비밀번호 인증으로 대체할 수 있도록 sshd를 구성하고 싶습니다. 하지만 매뉴얼 페이지/sshd_config 파일의 정보를 사용하여 이를 구현하는 데 어려움을 겪고 있습니다.

내 sshd_config:

Protocol 2
SyslogFacility AUTHPRIV
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile      .ssh/authorized_keys
PasswordAuthentication yes
ChallengeResponseAuthentication no
GSSAPIAuthentication yes
GSSAPICleanupCredentials yes
UsePAM yes
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
X11Forwarding yes
Subsystem       sftp    /usr/libexec/openssh/sftp-server

연결하면 개인 키가 전송되는 것처럼 보이지만 여전히 비밀번호를 입력하라는 메시지가 표시됩니다.

서버가 인증 메커니즘으로 둘 중 하나를 수락하도록 할 수 있습니까?

(예, 공개 키는 ~/.ssh/authorized_keys에 복사되었으며 이 구성으로 sshd를 다시 시작했습니다.)

더 많은 디버깅을 통해 키 쌍이 실패하지 않았음을 보여줍니다.
