V uživatelském rozhraní Presentation Server se zobrazí výzva k propojení PowerFlex MDM.


Přihlášení k prezentačnímu serveru 

 

Cause

V tomto scénáři koncový uživatel používá ověřování LDAP.

Prezentační server má token 8 hodin od okamžiku, kdy se uživatel přihlásí. Po vypršení platnosti 8hodinového tokenu se provede další pokus o přihlášení. Pokud se však tomuto pokusu o navázání připojení ke službě LDAP nezdaří, může dojít ke zrušení propojení serveru Presentation Server s clusterem.

Resolution

Propojte prezentační server s clusterem PowerFlex pomocí webového uživatelského rozhraní.
