L’interface utilisateur du serveur de présentation vous invite à lier un MDM PowerFlex.


Connexion au serveur de présentation 

 

Cause

Dans ce scénario, l’utilisateur final utilise l’authentification LDAP.

Le serveur de présentation dispose d’un jeton de 8 heures à partir du moment où un utilisateur se connecte. Une fois le jeton de 8 heures expiré, une nouvelle tentative de connexion est effectuée. Toutefois, si cette tentative ne parvient pas à établir une connexion avec le service LDAP, cela peut entraîner la dissociation du serveur de présentation du cluster.

Resolution

Reliez à nouveau le serveur de présentation au cluster PowerFlex via l’interface utilisateur Web.
