  • Applies to:
  • Plesk 10.x for Windows


When you try to login to your domain via ftp, it shows login form again, looks like credentials are invalid:

530 Login authentication failed
Login failed.

Things to try

Make sure that Parallels Plesk Panel is not installed on Domain Controller server, because DC does not have local user database.
It is highly not recommended to install Plesk panel on Domain controller. System requirements described in Installation and Upgrade Guide.
