The "Local System account" used to run the "Building Operation Enterprise Server" service does not have sufficient permissions for EBO/Active Directory integration. One function call from EBO to the Active Directory fails when EBO tries to fetch the groups for the user logging in.
The service account used to run the "Building Operation Enterprise Server" service must be able to read the token-groups-global-and-universal (TGGAU) attribute. The IT department or the Active Directory administrator needs to grant this explicit access to the service account by adding the service account to the built-in group in Active Directory called "Windows Authorization Access Group". For more details regarding the TGGAU attribute, see this article from Microsoft Support, Some Applications and APIs Require Access to Authorization Information.
