Titel
Error when accessing external/foreign domains in the GPOADmin console -
Beschreibung
When managing external domains with GPOADmin you may receive an error when attempting to access one of the domains.
Error message: System.IO.IOException; The read operation failed.
-
Ursache
The issue occurs due to additional security changes which have been implemented in the 5.11 release. -
Lösung
In releases prior to 5.11, all users had access to all domains per default. With 5.11 we are adding the Domain Users group for each domain to the security configuration of the live environment (see properties of Live Environment node). Other groups can be added. At the moment when attempting to browse any of the domains, the application will attempt a SID Lookup for the configured groups. A trust relationship between the GPOADmin server domain and the other "external" domains is required in order for the direct connection of the SID lookup to succeed.
We have created a defect ID to resolve this issue in a future release (TF00733744).
