For some reason i though that cached credentials expire, which is obviously not the case. Don't know where i picked that up from.
I don't think, by default, cached credentials expire.

Maybe they never do. I've got one system that's been off of AD for years and still works on cached creds, but it is 2003.

I looked it up before i posted and it doesn't seem possible to make cached credentials expire. That's why i found it so odd that i thought the did expire.

Well I thought that there was a way to expire them, too. That is very weird.

Yup, looks like once you get a machine off of AD physically, you can attack it forever.

Wow, just, wow.

Theres some built in safety from my understanding. The cached credentials are hashed twice, so at best they would only have access to that computer, it does not comprise the security of AD.

@travisdh1 yeah, I don't like that.

As far as I can tell, you can use the Windows RSAT stuff to manage the SAMBA4 domain controllers, GPOs should work... Dang.. I need to spin one up now, lol.
Let us know how that goes.

@scottalanmiller said he is going to do a writeup someday (soon?) on this process. (Replacing AD with Samba.)
I'll probably give it a go. We're down to less than 20 employees, so if it burns, it burns.

Is SAMBA4 better in a windows only environment or is it simply the best solution for hybrid environments?

In a Windows only environment, I don't know if it really makes sense. Assuming you have the license in place already, why not use the native platform? Doesn't mean a SAMBA DC doesn't make all kinds of sense when you don't have the licensing in place already.

Well, you need to maintain said licensing (ie refreshes etc). I'd rather move to SAMBA and use the licensing for other stuff or spend less if possible

They have licensing for 2003. This is a free update.

Huh?
He means I'm always going to have licensing in place

Well, I DCPROMOed the one physical DC last night. Nothing seems to have burned down.
I was having some DNS issues, but I think it was due to the fact that my machine was pointing to the demoted DC (which obviously had the DNS role installed) and it had been gutted by DCPROMO. I removed the role and everything seems OK thus far.
Though very few users are here. I'll feel better by like 10AM.

Did you update DHCP to no longer pass out the old DC as a DNS option?
Did you go through all the static IP devices and remove the old DC DNS info from them?

Yes and hopefully.
