OU and GROUPS. The Russian Doll way.


As I was reading stuff about Active directory, Organisational Unit and groups, I understood that most of them where misleading. Truckload of misleading documents that are written, I decided to tell my version of it. I didn't have any Windows server at hand to make some serious perusal.

So I decided to, first buy the cheapest but yet good computer that I could find on Ebay. I bought a computer for 50€... 2 NICs, and used a copy of Windows Server 2003 SP3 to get things right. Well I could not afford more at the moment... I resigned to install a Windows Server series (2003 here) on a fairly good computer ;-) To get the hack of this mysterious and tricky thing... I got it right at once.

My feedback is. It is not that tricky. As I know understand how it works. I'm glad to share it with you

Let's go.

So, how does this work ? Actually this is quiet simple and, straight forward. Once you have established your Active Directory to manage your Domain, you'll have to create your OUs. Then in your OUs, you'll have to create your Groups.

So, how to organize your groups ? First you will create your groups based on the activity of people. Let's say Sales for... Sales, and then include your salesmen in it. "But, Sales have only one person !" you'll say. Soooo ?  Ok then.
  • Create your Sales user. Call it salesman1 or, sl1for example.
  • Create a Global group called Sales.
  • Create 2 local domain groups called salesRW and salesR.
You're done. Now it is a matter of common sense. Move your user in the Global Group, then move your Global Group in the Local Domain Group of your choice. For instance SalesRW. To keep it small I'll say it goes like this :

[Users]=>[Global Groups]=>[Local Domain Groups]=>[NTFS properties]=>[Folders]

If you try to include a LDG in a GG, a Windows AD mechanism will insult you politely ;-)
So it is kind of foolproof here. What is next ? Next is the access to the resources.

What are Global Groups, Local Domain Groups ? Shortly :
  • Global Groups are groups that can interact in between domains.
  • Local Domain Groups are groups that can only interact in the local domain.
These groups are organized by an organisational Unit. An OU. The OU is managed by the AD, the AD which manage almost everything in the Local Domain anyway.

What type of resources on the local domain, is available for the SalesRW group ? Well, let's say you have a shared folder called "Best_Sales_this_month" You want salesman1 to have a read and write access to it. So you'll need to edit the folder properties and add the LDG SalesRW with read/write permissions on this very folder. Yeah ?

I will not go any further for the moment as, I think that if you understand just that you will be eager to go further all by yourself and say 'I made this !' :-)

To finish...

So, you see it is not rocket science. Unfortunately people who wants to learn it by the book may find it very hard (As I did). Which is to me pretty strange... Anyways, I'll hope to have made this more clear for some of us.

Rouge bleu.

I met this wine. Yes, I met it. Thanks to Sandy and Marc. It was in Lannion and we were sharing the evening meal. I brought an infamous Vouvray... Everybody had the politeness to say it was tasty... Well because of the peache liquor that was added in it beforehand... And because as usual I was broke.

Then a bottle of Rouge Bleu was opened and poured in every glass. I drink it and I was not able to express my pleasure. My brain was still at it. So the landlord said it "was not bad" but in fact it was gorgeous. So I noded and politely said "yes it is". Now, I reckon that it was shallow... I was having a hard on. My brain was going havoc. Give me another glass ! At once ! What a fine wine. So, if you like a glass of good wine. Do not hesitate. Go there :  http://www.rouge-bleu.com/ These are well made, very sensitive wines. Well if you are sensitive to wine...

CCNA in 1 day.

Is it possible to get CCNA certified in 1 day ? Yes it is. According to the liars with whom I am working with at the moment.
I am following a level 2 administration and management computing training. The duration of this about 8 months. We have got a lot to do. Windows server 200R2, Exchange. Oracle database. Linux. Helpdesk. Scripts. Office suite, back ups, disaster management, routers and of course as a mark of recognition for all of us, we have have an inscription to pass the CCNA exam.

The pace is barely possible to follow. One course busting another one out. But then again, are we supposed to be all knowledgeable about all of it ? No. We are not. Indeed an experienced IT professional would follow these training courses with amusement. Yes. 

This week our teacher had a major incident in his family. He had to go back home to sort  things out. He left us with some directions. Set up a switch and a router. Manually. Gather infos from a 2008 server and snmp tools. And of the top of it uses EON, launch CACTI and then manage triggers. "And if you got time make a note of it." That would be all. Ladie and gentlemen you have 1 day and half. ;-)

Ahaha. So let's get started. Despite all respects for the guidance all the guys and by the way the only girl of the class, decided to organize a cheat session. Yes. A cheat. session. And yes to get the CCNA.
 
To tell you the truth I was disgruntled. How can this be ? Does all of this means nothing. Apparently yes. I went to the elder (beside me) and asked him why he was doing this. He replied. " Well fuck it. I want it and I want a good job. So I'm gonna get it no matter what".

Unbelievable. And, the guy was so lame he did not know how to search in the cheat pages. 


Indeed. I did not participate. to the deal. Why would I ? Better be an outcast than a cheat partner.

Voo.

Or Le "vous"

In France, there is a subtle distinction in being old and beind adressed as a mature person by youngsters. This way is called "Vous" pronounced "voo", it is a mark a recognition, of respect for your age. I believe the same attribute does not exist in English. The closest would be "sir". But, in france sir is very formal. It is very academic and have very little in everyday life. Except "excuse me sir" which is the entry point of any polite and well educated way to ask some French you don't know, something. Using "sir" alone is more a mark of attack towards the person you address.

I have to recognize that I am going on my 50 but, somehow with a 25 years old mentality. I am still rebellious. Rebellious to stupidity, harshness, lack of manners. And yet I like my youth era music. Meaning the 80's indy  music. I have been hugely inflenced by junk music. I mean my attitude have. Now, I am recovering... It is said that you do not choose music but music chose you. Like it was a sexual preference set from the beginning. I don't believe it is entirely true but it is very relevant to any human. Isn't it right ?

Where was I ? Ah yes. "Vous"... I am not use to be adressed as "Vous".
I have to comply with it now I guess. I'm 50. Then, even if I feel that I don't need the effort to be threaten as an elder. I mean, not yet. It feels like I am granted something that I did not finish. Being mature. Or maybe I am and I fail to see it. Anyway I cannot tell the youngster that I am still young at heart. That's going to be a pleasant game anyways. So getting old is fun. Yes, sir.
