When you login with the default admin/admin credentials, it prompts you to change the password. It accepts passwords > 15 characters, and logs you out. You can then NOT login with those passwords and have to factory reset the unit. I've tried first and last 15 characters of the set password just in case. I can reproduce this at will.
If you set a password from within the Maintenance -> Account page, it gives you an error if you try to use passwords over 15 characters.
