I was wondering if there is any restrictions on password length? I ask because I set up a new FTP user, but the login kept failing. The user's password was a random 20 character password. After I shortened it to 15 characters, I could log in.
I just tried an FTP password of 30 "a" and it worked. I don't know if I have the patience to go through all the ASCII characters to find which one it didn't like.
