Today I want to test the function of connecting Delphi to AD，Teaching on the Internet，You can use "Component → Import Component"…” to import，But in actual operation，卻出現 “An error occurred while accessing OLE login。” Error message。
Follow the online teaching steps，Go to "Component → Import Component…」，After selecting "Import a Type Library"，Cannot see the "Active DS Type Library" item。
Then click "Add"，Select “C:\WindowsSystem32activeds.tlb” Later，will appear “An error occurred while accessing OLE login。” Error message。
解決方式
Execute "command prompt character"，Enter the following command
tregsvr -t -c C:\Windows\System32\activeds.tlb
Go back to "Component → Import Component…」，At this point you can see the "Active DS Type Library" project。
"Reference Link"
