I'M reading "Linux + Guide to Linux Certification" and I've come to samba and I'M having trouble understanding a few things. The book says I need to add a username and password on the Linux system that corresponds to the username and password on the Windows clients? And then another samba password that's the same as the Windows password. This raises a few questions with me. If a lot of the servers out there are Linux servers I doubt they all have a username and password for the millions of clients they get per day/month. I'M setting all this up in part just to learn Linux, networking, and servers and I may use it as a local media server for my house. So how would a devices like my D-Link media streamer or my WD TV Live Plus take advantage of such a server being that they don't have usernames or passwords? Also, Linux wants usernames to start with a lowercase letter and all my Windows usernames start with a capital, how's all this to work out? Thanks.
