Bit locker password microsoft full#

But what that blog does not tell you, is that with LDP.exe, we can go far beyond whatвЂ™s possible using the delegation of control wizard. So to be honest, I got the idea for the key part of this article from that Microsoft blog post.

Bit locker password microsoft full#

For the 'dumb' delegation of control wizard, it is true, but there is a way to access those without full access and it requires you to use adminвЂ™s old friend LDP.exe, which is a tool built-in to Windows 10 and also the server OSвЂ™.ДЇrom the Microsoft blog, you may gather, that what we need to do, is grant the so-called вЂњcontrol accessвЂќ in addition to merely read access - then the recovery passwords are accessible, read-only. These objects are hidden for other users in Active Directory.ДЇortunately, this is kind of wrong. Google that, please, you will find even more misconceptions, like for example on ДЄll objects created with the Confidentiality bit set to 1, are only available for users, who have full control access to that object. Microsoft has further protected access to these passwords, setting that bit, and the delegation of control wizard does not know what to do with it. To protect attributes like this, they can be marked as вЂњconfidentialвЂќ.ДЄha, so there we have it, the вЂњconfidentiality bitвЂќ is what this is all about. Some attributes should inherit permissions, but should not be readable by вЂњjust anyoneвЂќ. Normally in AD, all attributes are readable by вЂњAuthenticated UsersвЂќ. Imagine, this should concern bitlocker admins since server 2008 came out.but not before 2011, a Microsoft employee wrote this blog post: which names it: Googling reveals, that Microsoft documentation on this topic is hard to find. So whatвЂ™s wrong here, why are we unable to grant read permissions only? Please imagine what full control impliesвЂ¦ our colleague can not only read the passwords, but he himself may delegate access and enable other users to read these passwords, or even decide to delete the passwords (OK, letвЂ™s call it вЂњaccidentally delete themвЂќ). And what do we do now, turn to the вЂњbig GвЂќ and search the internet for a solution? Or will you rather experiment with the permissions? Back in the day, I did the latter, just to find out, that unlessВ we grant FULL CONTROL, it will not work. Readers, how many of you arrived at this point? Quite a few, I assume. In fact, nothing has changed, he cannot see the passwords. Loser in this example) to delete.ДЄfter applying this, you would surely test it with your colleagueвЂ™s account. Keep in mind, that we wanted to apply only read permissions and not enable our colleague (Mr. It turns out to be hidden well, but in the end (remember, bitlocker used to be called msfve 'Microsoft Full Volume Encryption'), you might find it should be possible like this: Well, normally, you will use the delegation of control wizard, when it comes to delegating specific permissions in AD, so letвЂ™s see if we can use it. Now imagine, that for your next vacation, you plan to enable a trusted colleague to read the recovery passwords of a certain OU for recovery purposes: if someone forgets his PIN, they should ask you colleague to help them out. Recovery passwords, however, give you full control over the drives.

Furthermore, these passwords are not comparable to PINs, because, with PINs, you are only able to start the machines, so a thief, that has somehow acquired such a PIN, will not be able to access the data on the drive. Please be aware, that without having these recovery passwords, you are facing data loss, as soon as the end-user forgets his PIN. Imagine you have applied bitlocker to all your machines and you use Active Directory to store the recovery passwords. I find it relevant because the usual way of using the delegation of control wizard cannot satisfy the need for least privilege and we need to use a largely unknown method instead, which will be described here. This article is meant for system administrators, who try to apply the principle of least privilege when it comes to Active Directory.
