I will try my best to explain;
The main reason is time. We want to be able to get the thing working without spending every evening for a month typing long strings into a terminal for it to still not work at the end. Many of us noobs aren't used to linux / raspbian / programming and are just trying to follow guides to help us meet our end goals. We execute sudo command after sudo command not having a clue what its doing or why we are doing it - hoping it will "work". When we try to read further into the subject - people who are in the know make many assumptions of what people will already know when reaching their sites and miss out 'obvious' parts as they should already be done / known - result....it doesn't work. I understand that it is all about learning however, when you are constantly back tracking trying to get one thing working and then you have to back track to fix the fix and then back track to fix the fix before fixing the fix, you get to the end of your tether and reach out for help. Why can't anyone write a nice, clear guide that explains how to do this and include a why it didn't work section for problems like mine. Because, although I'm sure your answer is excellent...I'm still no clearer on what I need to do.
Whilst I can understand what you are saying and to a certain extent why you are saying it, I still don't understand why people will believe things written on a random website, but either don't believe things written on a packages wiki or never think to look there.
Just this week I have seen a couple of posts on the Samba mailing asking why a DC doesn't work after they faithfully followed some web post they found. The reason was, the instructions they followed were badly flawed and probably written by someone who had done the same thing, followed a flawed howto.
If you follow the wiki page I posted a link to, you should get a standalone Samba server, if you don't, I want to know why. I can then help to get your standalone server fixed and then fix any problems on the wiki page. If you don't follow Samba's wiki pages, but follow some howto you found out there on the internet, whilst I can try and help you fix your server, I cannot fix the howto, I do not have write access to it. I have pointed out glaring errors to a couple of howto's my attention was drawn to, the problems still haven't been fixed.
