Brugergrænsefladen i præsentationsserveren beder dig om at tilknytte en PowerFlex MDM.

I dette scenarie bruger slutbrugeren LDAP-godkendelse.

Præsentationsserveren har et 8-timers token fra det tidspunkt, hvor en bruger logger på. Når 8-timers tokenet udløber, gøres der et efterfølgende loginforsøg. Men hvis dette forsøg ikke kan oprette forbindelse til LDAP-tjenesten, kan det medføre, at Præsentationsserveren fjernes fra klyngen.

Knyt præsentationsserveren til PowerFlex-klyngen igen via webbrugergrænsefladen.
