In de gebruikersinterface van de presentatieserver wordt gevraagd om een PowerFlex MDM te koppelen.


Aanmelden presentatieserver 

 

Cause

In dit scenario gebruikt de eindgebruiker LDAP-authenticatie.

De presentatieserver heeft een token van 8 uur vanaf het moment dat een gebruiker zich aanmeldt. Nadat het token van 8 uur is verlopen, wordt een volgende aanmeldingspoging gedaan. Als deze poging echter geen verbinding met de LDAP-service tot stand brengt, kan dit ertoe leiden dat de presentatieserver wordt losgekoppeld van het cluster.

Resolution

Koppel de presentatieserver opnieuw aan het PowerFlex-cluster via de webinterface.
