SSSD는 su : LDAP 비밀번호를 사용하여 LDAP 로그인을 거부합니다.

10

사용자 계정으로 LDAP 서버를 설정했습니다. 이 LDAP 서버에 대해 인증하도록 Rails 애플리케이션을 성공적으로 구성했습니다. LDAP에 대해 인증하도록 SSSD를 구성하려고하는데 개별 사용자 비밀번호를 좋아하지 않습니다.

오류:

$ su - leopetr4
Password:
su: incorrect password

SSSD는 사용자를 인식하지만 암호는 인식하지 않습니다.

$ id leopetr4
uid=9583(leopetr4) gid=9583(leopetr4) groups=9583(leopetr4)

사용자 레코드는 다음과 같습니다.

# ldapsearch -x -W -D "cn=admin,dc=my_domain,dc=com"  -H ldaps://my_hostname.my_domain.com "(uid=leopetr4)"
Enter LDAP Password:

위의 base64 디코딩 후의 사용자 비밀번호 해시는 다음과 같습니다.

{SHA}oRNO1j31wmt5HVEafcm5f/SRfjo=

그것은 정확히 slappaswd -c {SHA} "that_password"

  1. SSSD에서 왜이 사용자로 로그인 할 수 없습니까?

  2. 기본 {SHA}해시 와 일치하도록 SSSD를 구성하기 위해 수행해야 할 작업이 있습니까?

  3. 어떻게에 대한 인증의 차이점 파악 않는 login과에 대한 인증 su/를 su-l?

sssd 로그에 따르면 sssd는 모두 인증 한 다음 액세스를 허용했습니다. 배포에서 / var / log / secure 파일 또는 이와 동등한 파일을 조사하여 PAM 메시지가 무엇인지 그리고 다른 PAM 모듈이 작동하는지 확인할 수 있습니다. tls_reqcert = never를 사용하는 btw는 좋은 생각이 아닙니다. CA에서 신뢰하지 않는 인증서도 허용되기 때문입니다. 마지막으로 su에 의한 잘못된 비밀번호 메시지는 무엇이든 의미 할 수 있습니다. 유틸리티에 기본 오류 메시지 일뿐입니다.

또한 로그가 인증 실패를 캡처하도록 질문을 편집 할 수 있습니까? / var / log / secure가 인증 실패를 표시하더라도 sssd_be 로그는 성공을 표시합니다. (2015 년 11 월 27 일 21:15:54) [sssd [be [LDAP]]] [be_pam_handler_callback] (0x0100) : 보낸 결과 [ 0] [LDAP] 동일한 PAM 로그인이 캡처되고 PAM 응답자 로그가 있도록 파일을 편집 할 수 있습니까?

@jhrozek 나는 다시 캡처 /var/log/secure하고 /var/log/sssd/*.log출력했습니다 su - leopetr4.

흠, 정말 이상합니다. 도메인 로그에 다른 것이 있습니까? debug_level을 높일 수 있습니까 (10이 가장 높음)? btw sdap_save_user 소스를 확인했는데 UUID를 가져 오는 데 실패하지 않았습니다.

이 질문을하기 위해 답을 사용해야해서 죄송합니다 ...

출력 결과 : authconfig --probe및 getent passwd leopetr4

시스템 인증이 비밀번호 인증과 동일합니까? PAM 로그인 파일도 제공 할 수 있습니까?

sssd.conf에서 cache_credentials = false를 설정하고 테스트하는 동안 캐시를 지우려고 할 수도 있습니다. sss_cache -E

그것은 만족스럽지하지만 것 su - leopetr4그리고 ssh leopetr4@my_hostname내가 질문에 현상금을 설정 한 후 바로 작업을 시작했다. 나는 그것이 갑자기 시작 되 자마자 작동을 멈추는 것이 좋지 않기 때문에 그것이 분명한 결론에 도달하지 못한 이유에 대해 생각하는 데 시간을 보냈다.

내가 기억하는 한 가지 변경 사항 은 및 에서 pam_password설정을 전환하는 것입니다 ./etc/pam_ldap.confmd5exop

#pam_password md5
pam_password exop

그러나 부서진 상태에서 작동 상태로의 변경은 즉각적인 것이 아니므로 주저하지 말고 변경 사항으로 귀속됩니다.
