Hi Hans
Thank you for your answer but...
1 - in the left pane of edtManager I can see just anonymous, administrator, guest and aspnet, as users. Who they are and where they came from I really can't figure out ;-) I'm joking, in the sense that I know that these are the local (to my machine) users but my pc is in a domain and it could be useful if also the domain users would be listed there
2 - As I wrote, I tryied to configure users in the blabla/etc/passwd file (also using the blabla/bin/mkpasswd -d > blabla/etc/passwd) but...well, I'm here asking my question ;-)
Anyway, added a new user (ftptest with ftptest as password), enabled in the Manager interface but the server still answer "530 Login incorrect"...
Any hint?
