I have connected up a usb disk onto the usb port of a 2830v2 and setup the ftp user accounts up to access the usb disk.
However, when I get prompted for the user account to be entered, I enter in the details and hit login and it returns with another login prompt.
If I hit cancel, I just get a blank page.

Usernames are in lower case and passwords are 1 caps, 1 number and no more then the allowed 11 characters.
