[Solved] Usage of Active Directory Credentials for Microsoft BitLocker

Secure Authentication using Active Directory Credentials

Beginning with Windows 8, Microsoft BitLocker supports password authentication without any TPM requirement. To use the BitLocker password protector the TPM support need to be disabled on a client machine. This gives great encryption possibilities for older clients not offering a modern TPM chipset. By the use of the password protectors Windows Server systems as well as virtual systems can be encrypted.

Authentication Limitations

Unfortunately, the password protector does have multiple limitations, we asked customers to summarize:

  1. Missing username in the authentication process. The password is a machine authentication and does not support multiple users.
  2. The password does not synchronize with any Active Directory password; therefore users need to memorize the BitLocker boot password in addition to the domain credentials for Windows logon.
  3. BitLocker does not support single sign-on after successful pre-boot-authentication.
  4. The pre-boot password is not stored centrally therefore helpdesk support is not available for the password protector.
  5. In case of a lost or forgotten BitLocker password users need to handle the 48-digit Microsoft recovery key to unlock the client.
