Replacing AD in Enterprise?

  • SpinRite v6.1 Release #3
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Hi guys,

As time goes on and Windows becomes more and more obviously a security nightmare, I was wondering about alternatives to Windows in an enterprise setting.
The thing that I always wonder about is some sort of centralised Identity and Access Management solution to replace Active Directory.
Does something like LastPass or BitWarden offer cloud-native solutions that allow a similar solution to the likes of SSO in an AD environment?
And for replacing group policy as administered by AD, do solutions like Ansible offer similar features?
Also, thinking about recent topics covering software defined networking, would something like TailScale offer suitable VPN solutions?

If you were planning to build an enterprise solution from scratch without MS Windows in the mix, what would it look like?

Thanks in advance. :)
I'd probably start with Azure AD, but there are alternatives.

I took a modern approach to this question since I would go 100 Zero Trust with heavy use of the cloud. So I looked up the identity platforms that Palo Alto's Zero Trust service supports. They are Azure AD, Okta, Google Identity, and Ping. I would want the product that is most compatible with the services that I use, and I expect that to be Azure.

Gartner lists some more competitors:

The group policy question is a good one. It assumes that you're going to continue using Windows computers. This is another area where the Microsoft tool will likely be more attractive than alternatives.

I haven't spent much time on AWS Identity Services. That could be an interesting way of solving this problem with the same considerations as the other services.
