Web/FTP Server

Greetings At work I have Linux Machine 2.2.16 SuSE7.0 Pro. The Linux machine its up and running. I want to setup my Intranet for my LAN user by giving each user the possiblity to authenticate him self (username + password) to get/download his ownfiles (Txt,Xls,Doc, Rtf) via Internet Expolorer from his machine. it means the linux machine should run FTP server as well beside apache. Each user should have his own home directory such as http://X.X.X.X/user1 ... etc. then should a window appear to authenticate him self to download the files. Do you know how could i set up the above? Any input would be really appreciated. -Pons pls send your input to my email. thanks in advance
