I recently installing a Trinton Unified Security console (v7.8.1), and stuck on the installation of Directory Service Access. The account I used would resulted a pop of "The installer cannot verify your domain settings. Please clear the credentials on this page to continue. You can configure directory service access for affected components after the installation is complete"
It is strange, because the same credential was successfully able to joint the V5000 to join the domain.
Any suggestion?
