Dell Unity: 5.5로 업그레이드한 후 Uemcli 명령이 실패하고 "지정된 인증서를 검증할 수 없음"이 표시됨(고객 수정 가능)

• Uemcli Unity OE 5.5 CLI에서 실행 중인 명령이 오류와 함께 실패했습니다. "Unable to validate the specified certificate. (Error Code:0x1000100)".

• 최신 Uemcli가 설치된 Windows 클라이언트 및 Linux 클라이언트 또는 5.5 이전의 Unity OE에서 실행할 때 동일한 명령이 실패하지 않습니다. 
• 이 문제는 CA 서명 인증서가 지정된 Unity 시스템에서만 발생합니다. 
• 스크립트가 여러 번 실행되면 업그레이드 전 상태 점검도 실패합니다. uemcli 명령을 사용합니다.

• Unity로 가져온 인증서 체인 고객은 루트 CA 인증서를 포함하거나 포함하지 않을 수 있습니다. 이 문제는 가져온 인증서 체인에 루트 CA 인증서가 포함된 경우 Unity에서만 발생합니다. 
• 해결 방법이 있지만 근본 원인은 아직 조사 중입니다. 근본 원인을 사용할 수 있을 때 KB가 업데이트됩니다. 
• 가져온 인증서 체인에 루트 CA 인증서가 포함되어 있는지 확인하는 방법에는 두 가지가 있습니다. 

방법 1: 

이전(예전) 메시지로 이동과 openssl s_client -connect <Unity mgmt ip:443> -showcerts 을 클릭하여 인증서 체인을 나열합니다.

루트 CA 인증서는 자체 서명된 인증서이며 항상 주체와 발급자가 동일합니다. 

 2 s:DC = lab, DC = peeps, CN = peeps-PEEPS-DC-CA   <<<<<<
   i:DC = lab, DC = peeps, CN = peeps-PEEPS-DC-CA   <<<<<<

방법 2:

Windows 업그레이드를 실행하라는 프롬프트에 아래 내용이 표시될 때까지 openssl x509 in <certificate file> -text -noout | grep -E "Issuer:|Subject:" 인증서 파일을 클릭하여 인증서를 나열합니다. 

00:50:09 root@VIRT2213Y2XXXX spa:/cores/service/user# openssl x509 -in unity_pod1.pem -text -noout | grep -E "Issuer:|Subject:"
        Issuer: DC = lab, DC = peeps, CN = peeps-WIN2022-CA
        Subject: C = IE, ST = Cork, L = Ovens, O = DellEMC, CN = peeps-pod1-unityvsa.peeps.lab

        Subject: DC = lab, DC = peeps, CN = peeps-WIN2022-CA  <<<<<<<

해결 방법:

• KB000021122 따라 루트 CA 인증서를 포함 하지 않는 새 인증서 체인을 Unity로 가져옵니다. 

참고: 

• Unity 인증서가 루트 CA에서 서명된 경우 Unity로 가져온 인증서는 Unity 인증서 자체인 단일 인증서여야 합니다.  
• 중간 CA에서 서명한 Unity 인증서의 경우 인증서 체인을 순서가 지정된 전체 시퀀스로 구성해야 합니다. 이 체인에는 다음이 포함되어야 합니다.

1. Unity 서버 인증서(최종 엔터티 인증서),

2. 계층 경로의 모든 중간 CA 인증서,

3. 클라이언트의 신뢰 저장소에 이미 있어야 하는 루트 CA 인증서는 제외됩니다.

체인은 최종 엔터티 인증서에서 직접 발급자까지 순서를 지정하여 클라이언트가 미리 신뢰할 수 있는 루트 CA에 대한 신뢰 경로를 추적할 수 있도록 해야 합니다. 예:

Unity Certificate → Intermediate CA 2 → Intermediate CA 1
