In KDE , if i am browsing the windows network by using konqeror , you can see all the domains in the network and machines which are part of these domain . But , when i am trying access to one machine , username-password dialog box appears . After providing username & password credentials , a user can go inside that machine and he can access the shares which are in that machine . If you try to access same machine second time , you won't get username-password dialog box . Konqeror has capabilities to cache the password , but this is not permenent for windows networks . Kwallet also doesn't helping me to solve this issue.
