[Samba] Need Share Advice

[David L Nickel]

I am going to be backing up my web server through a Samba share.
My webserver has three partitions; "/" "/usr" "/www"

I would like this share to be password protected and hidden. One of the
problems
I ran into is getting a password prompt for the share ( by default it logs
me in as guest).
I was wondering if anybody had some type of share template I could go by.
Any help will be greatly appreciated
Thank you
David
