Dynamic group membership to work around no nested security group support for Active Directory

  • 772

My problem is that I have a number of network administration applications like SAN switches that do not support nested groups from Active Directory Domain Services (AD DS). These legacy administration applications use either LDAP or LDAPS.

I am fairly sure I can use Active Directory Lightweight Directory Services (AD LDS) and possibly Windows Authorization Manager to work around this issue; however I am not really sure where to start.

I want to end up with:

  • A single group that can be queried over LDAP/LDAPS for all it’s direct members
  • LDAP proxy for user name and password credentials to AD DS
  • Easy way to admin the group, ideally the group would aggregate the nested membership in AD DS.
  • a native solution using freely available components from the Windows stack.

If you have any suggestions or solutions that you have previously used to solve this issue please let me know.

    I had a similar problem at a previous job. We ended up doing what Jscott did, which was to create specific groups just for those special apps. These groups were created in batch-mode once a day (that was as often as we needed) based on what the nested-groups had in them. Unfortunately, I no longer have the source for that, but we leveraged a combination of dsquery and powershell to build these special groups.

    $masterList=dsquery group $DNOfNestedGroup

    The problem there is that this list will return both users and member-groups. The power-shell logic has to disambiguate and recurse into the child groups, only adding uniquely-new members to the master user list. Once you've build the master user list, you can then use dsadd to create (or update) a group with static membership.
