프레젠테이션 서버 UI에 PowerFlex 클러스터를 연결하라는 메시지가 표시됩니다.

영향
최종 사용자로 로그인할 수 없습니다. 프레젠테이션 서버를 PowerFlex 클러스터에 연결해야 합니다.
Cause
영향
최종 사용자로 로그인할 수 없습니다. 프레젠테이션 서버를 PowerFlex 클러스터에 연결해야 합니다.
근본 원인
이 시나리오에서 최종 사용자는 LDAP 인증을 사용합니다.
프레젠테이션 서버에는 사용자가 로그인한 시점부터 8시간 토큰이 있습니다. 8시간 토큰이 만료된 후 후속 로그인이 수행됩니다. 그러나 이 시도가 LDAP 서비스와의 연결을 설정하지 못하면 프레젠테이션 서버가 클러스터에서 연결 해제될 수 있습니다.
Resolution
해결 방법
웹 UI를 사용하여 프레젠테이션 서버를 PowerFlex 클러스터에 다시 연결합니다.
