I am running openSUSE 10.2 and can authenticate against Windows Server 2003. it creates new profiles on the local (linux) machine but I want to be able to pre-configure web browser proxy settings, default printer settings and default mapped network shares on the windows server. How do I do this?

I don't have a Linux installation to check against but UNIX systems have a skeleton directory that can be used to initialize new accounts. The commands for creating accounts generally allow you to specify a skeleton directory to use as well, especially if you have different types of users to add (i.e. /etc/skel_default, /etc/skel_appset1, /etc/skel_appset2, etc...). Take a look and see if you have a /etc/skel directory or check the man pages for useradd.
