Further to my adventures of reinstalling my main machine, I have discovered the New Samba. What a shock! Anyway, they've gone full out with security, and it makes difficult for a small network, where all you want to do is watch legal movies on your wd-live. :)
First off, they now totally pooh-pooh SWAT which I used to use to configure the samba server. Now I have to use gadmin-samba. The worst is that they also diss the use of security=share, which was a convenient way to blow out all the security. After reading everything on the Internet, I had to settle on having a samba user for my exported drive. The wd-live could handle it. No more 'anonymous'!
Update: It's security=share, now you can only use 'user'.
