Hi there,
The problem is about KIO and KUrl.
I set The Username/Password for a GET/POST request to KUrl url via KUrl::setUser() KUrl::setPass() The result is something like: http://USER:PASS@domain.com/
And then do a KIO::get/post/... , But I see an Authorization Dialog to enter the credentials again, So, the credentials I already set by aren't used! :-/

Is it a bug!? Or what?
If user sets KWallet off, the program will ask for user/pass every time want to connect!

You can see this situation on Twitter Plasmoid / Microblog plasmoid and Choqok the Microblog client!

I have the KDE 4.2.2 Maybe this already fixed for 4.3 :-/ Sorry for interrupting you. I don't think i should fill a bug report for it.

Regards,
Mehrdad
