How can I configure my Active Directory LDAP server (Windows 2008) to enable certificate verification and client authentication.

Thanks, Gayathri

  • What PKI Infrastructure do you have? What application do you want to use which does cert auth?

I assume that you want to import a certificate from an arbitrary CA. A Windows CA is able to publish certificates directly to an active directory user.

To map a certificate to a user account

  1. Open Active Directory Users and Computers.
  2. On the View menu, select Advanced Features.
  3. In the details pane, click the user account to which you want to map a certificate.
  4. On the Action menu, click Name Mappings.
  5. In the Security Identity Mapping dialog box, on the X.509 Certificates tab, click Add.
  6. Type the name and path of the .cer file that contains the certificate you want to map to this user account, and then click Open.

Confirm that both the Use Issuer for alternate security identity and the Use Subject for alternate security identity check boxes are selected.

After this, you should be able to authenticate with the certificate against this user. Your application of course has to support Active Directory Certificate authentication.
