Hi, I've deployed FIM CM on a very large Active directory (250000+ users) everything has been delegated correctly and I am having two problems when looking up users for smartcard enrollment. All normal usernames are based on the following standards: Standard Accounts: Acbd123 Service Accounts: svc123 Admin Accounts: adm123 When I try to lookup users based on "abc" i get an 'ADSDSOOBject' Failed with no error message available, result code: -2147016669(0x80072023). I can however successfully search for service and admin accounts. Then I try to do a lookup of the actual login Name i.e. abcd321 i get the following error: "value does not fall within the expected range" Can anyone please help
