Korgers:
I was wondering if any o you guys have configured a domain with Samba as PDC with M$ terminals and other M$ servers as BDC. I am in the middle of the research and I would appresiate any tip or comment on it, pros and cons, advice ect.
Thanks very much.

My thought is don't do it. We have had too many problems with supposed LAN admins setting up Samba servers that have cause nothing be pain for all Microsoft clients on nearby segments. Having a non-Micorosft OS pretending to be and performing the main role of a Microsoft domain is not something I would entertain.

Thanks lot for the answer Howard. I get your point.

I am after an enterprise solution like SuSE FE, solution that could basiclay handdle M$ roaming profiles and main PDC functionality on a mixed enviroment.

Truth is I am kinda new to Linux but seems like a fairly reasonable path to ride, specially intresting path on learning both sides of the jungle.
Company heads agree a lot in not paying CALS or whatever the word "LICENCE" has a name. We low budjet here.
About the "supposed LAN admins" is something to be taken into account, PDC work is too important to be given a shot just like a chance.

I would like to hear some more thoughts of you colleagues.

Thanks.

Je Joser,
I don't believe you can circumvent the need for CALs if you use "M$ terminals and other M$ servers as BDC".

indeed.
but jose actually would save something if also the BDC's were to run samba.
anyways, the easiest start point is to go with bdc and once got all that messed up, go for the PDC seat.

Are you still seriously considering NT4-based technology?!

Only practical usage Samba has to me is as a compliment to on a *nix or AIX machine in an MS environment, to access the filesystem or whatever.

I am trying to get rid of NT 4.0 Servers and move on, believe me that no one more than me wants to put the 2003 cd on the PDC server and update but it is a time for me to be more objective about the clients posibilities and structure. My personal thought is that if there is gonna be reduced investment is done basically on the hardware side.

Les about the M$ BDC´s there is an issue there cause most probably I will have to mantain two user databases linux-M$ wich is sort os a pain in the a$ but I will come back with sort of solution out of it (if there is one) to post it out for you guys.

Good point Jooel about the strategy. Thanks boys.

What's the point in using Samba as the PDC fi the BDCs are still using a Microsoft OS. You're not saving on license costs, you're introducing complexity, adn you're limiting functionality to whatever Samba offers. You're better off either to iplement a clean Samba/LDAP/NetWare directory or go for Active Directory. You can still incorporate Samba-based file/prin-sharing without making the Samba-computer the PDC.

Jose,

Here are some questions I posed for a very knowledgeable Unix/Linux admin Kirk Waingrow of http://www.ugu.com/
http://www.ugu.com/sui/ugu/show?info.book

Let's say that you have a new Company of 5,000 and you don't want to run any Microsoft software at all. Is it possible and how would it be handled best?


1. Servers (Linux, Fedora, etc..)

Our file servers here are all running Fedora with 3ware raid controllers and are clustered for redundancy using “Heartbeat” and “DRBD” both freeware.
See the following:
DRBD Start
Linux-HA Project Web Site – home of heartbeat packages
Linux Magazine | November 2003 | FEATURES | Highly-Affordable High Availability - linux-ha + drbd how to – very good, written by the main heartbeat developer
Single System Image Clusters for Linux (SSI) – next gen cluster, not using this time around due to lack of proven drbd integration (critical) + lack of 2.6/xfs support (nice to have)
Enterprise Volume Management System
Fedora Project, sponsored by Red Hat
http://atrpms.net/dist/fc2/drbd/ - drbd 0.7.5
evms 2.3.3 (3 months old, not most recent, but has all needed features)
Heartbeat


2. Desktops, Redhat, Suse, etc..
You may want to take a look at Linspire, I believe they have a buy once use many.
The World's easiest desktop Linux
They also have an upgrade path and I believe remote deployment as well. Otherwise, sure take time and look at Redhat and Suse to see what provides the best deployment strategy.

3. I assume one of the Office suites is still available for free.
There are:
kOffice: KOffice is a free, integrated office suite for KDE
OpenOffice: OpenOffice.org is a free productivity suite compatible with all major office suites.

4. How do you manage/report on all the servers and desktops…. i.e.
(When a new patch for an application or the OS comes along how do you update 5,000 desktops and servers?)
Each flavor (RedHat/Suse/LinSpire) has their own way of doing it.

5. Can you run any type of centralized scripts against the client desktops?
Sure. As long as the remote access is provided, you can set scripts up to push or pull. You can use crontab to perform updates or manually do it.

6. Does Linux support some type of centralized directory similar to MS Active Directory that Linux desktops could belong to?
good old unix/YellowPages . Also check out PHP, LDAP.

7. How can you selectively prevent certain users or certain machines from running specific applications.
Permission control is available at the user and group levels.

8. If possible would achieving the above results require a very advanced Linux Admin (how many on staff) or within the realm of general system Admins.
You should have at least one Senior Level Admin (5-7yrs - $70-80k), 1-2 Intermediate level Admins (2-4yrs- $60-70k).

9. How do I build so many machines with linux fast?
SystemImager is the equivalent to Ghost: http://www.systemimager.org/

Resource book on migrating from Windows to Linux you may want to review

Windows to Linux Migration Toolkit

Hope this information is helpful Jose...

Also; just keep this little annoying fact in he back of your head:
Licensing fees is almost always a minor factor in TCO for large as well as small companies. Even the more expensive licensing models.

still little confused...
if talking about samba, isn't samba the linux AD tool?
so what's the problem of running fullblooded w2k ad with it?

samba will participate in an AD environment but cannot be the root of it. I also dont think it can be a AD DC as the support is not quite their due to the lack of published info.

however using ldap samba can do much the same as AD

Not AD but DC yes.
Doc thanks very much for the data man.

Jens, agree on the fact that is less painfull to choose on one way or another but there are several remnant legal (compulsory) apps that need to run in M$, so far I have decided (by now) to place them in an XP machine to open the way for full migration.

You say that is the same to have Oracle database in a small company than MySQL FE that could afford a relative good database service? TCO politic might be a minor factor in developed counties but not in "all" counties.

Thanks very much for your thoughts and comments boys.

@Jose, no, I don't mean comparing apples and oranges An Oracle db would most likely be a waste on a small company either way. For a small business that needs SQL, MySQL or a SBS 2003 Premium would probably be a better choice.

What I'm saying is that licensing is generally stared at with way too blind eyes. Is is most often the smaller piece of the whole picture.

Why introduce Samba when there's no need? It WILL just cause problems, sooner or later. A real Win license is just a handful of consulting hours - way less than the one's you'll be spending trying to get a foreign technology copy to work in your environment.

I am very aware of this risk I might be taking, i know the money you dont spend in licence you might have to spend it in cosulting hours. I really understand what you are saying.

Believe me I have been doing plenty of research and informs for upper level being objetive about the issue and the feedback I get is what I have mentioned.

I have the thought that both desitions (m$-Linux) are ok for me, get M$ (stay confortable) or turn to Linux (learn and run) but what I am really sure and I speack it out loud is that we cannot stay running under NT 4.0. That is something I cannot concieve and is more riski than taking "any" desition.

BTW masken. Thanks very much for your thoughts.

Well I'm a little damaged from being a consultant for too long I always opt for the K.I.S.S. solutions hehe... cause noone is willing to pay for anything else.

Pardon masken, what would the "K.I.S.S. solutions" should be ??.

Could be added to the list.

k.i.s.s. solutions are the ones that don't take brain power when they are produced.

lol @ lonk yeah.. that's right, but I'd formulate it a little differently: it's the solutions that takes more brainpower in planning and decision, and less hours of implementation and maintenance

It means "Keep It Simple Stupid"

In other words, what you're trying to accomplish should be as un-complex as possible
