Wget не сохраняет cookie как надо

[MMMMM]

Есть Web-приложение ASP.NET (для внутреннего пользования компании). Не могу авторизоваться на нем с помощью wget. Для авторизации используется Form Autorization, то есть надо через cookie заполнить поля и запросить страницу.
Операционная система Linux RH
Скрипт на шеле:

wget --save-headers -d -o log1.txt --save-cookies cookies.txt --keep-session-cookies \
http://IP-address/Def/Login.aspx --cookies=on

wget --save-headers -d -o log2.txt --load-cookies cookies.txt --keep-session-cookies \
http://IP-address/Def/Login.aspx --cookies=on \
--header='Cookie: ctl00_ContentPlaceHolder1_Username:name' \
--header='Cookie: ctl00_ContentPlaceHolder1_Password:parol'

в самой странице при втором вызове wget сервер прислал:
Your browser is rejecting cookies from this website. You will not be able to log in until you fix this.

Помогите разобраться со скриптом. Можетя чего не так с cookies делаю?
