Error on Users list configuration in installation

2

Hi everyone!

This is not my first installation of WebCon BPS, but it is the first time I experienced this error.

Everything worked fine until Users list configuration step. When I try to configure the local AD as source for synchronization, I receive the error "The parameterized query '(@Email nvarchar(4000),@DisplayName nvarchar(4000),@BpsId nvarch' expects the parameter '@DisplayName', which was not supplied."

I assume, that for one of my service accounts the property display name is not set? I have double checked this, but all users in AD have display names.

I also tried synchronization with Azure AD, but receive the same error message.

Any ideas?!
