프레젠테이션 서버 UI에 PowerFlex MDM을 연결하라는 메시지가 표시됩니다.


프레젠테이션 서버 로그인 

 

Cause

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

웹 UI를 통해 프레젠테이션 서버를 PowerFlex 클러스터에 다시 연결합니다.
