After MSSQL database restore, following message is displayed in Parallels Plesk Panel interface:
Warning: Database was restored successfully, but some database users require your attention. There are several orphaned users that should be repaired to function properly. View users now.
Link "View users now" leads to non-existent URL
/domains/databases/db_edit.php3 which prompts error 404 from control panel.
The problem is caused by error in the product which is going to be fixed in future releases.
Run following command for each database user of restored database to fix orphaned users:
"%plesk_bin%\dbbackup.exe" --repair-orphaned-user -server=localhost -server-login=MSSQL_ADMIN_LOGIN -server-pwd=MSSQL_ADMIN_PASSWORD -database=database_name -db-user=db_user -db-user-pwd=db_user_password
