Open Source Identity Solutions

I was asked by a colleague today to provide sources of analysis comparing Open Source IDM Solutions. I think they were looking for comparisons to closed source solutions but there is not a lot of that out there. I provided the following list as a starting point.

I generally like to save time (avoid searching for this again in the future) so I decided to put what I found here. If I am missing anything please let me know and I will update the list.

Provisioning/User Identity Management:


SSO/Access Management/Authentication:


Directory Services:

    Hey Brad – don’t forget about dotnetopenauth. It’s a .net library which can be used to enable OpenID, Oauth and IMI.

    Hi Brad, also has an open source OpenID Connect platform called the OX.

    It’s been getting interest from a number of telecom carriers and was just deployed by a major electronics manufacturer in a new line of tv devices.

    Hello Brad, Thank you for these links.

    Is Oracle Fedlet not available anymore? Do you know?

    I am trying to locate the ZIP file( following one of your previous posts from 2012 on using Fedlet for federation. So far I have been unsuccessful in locating it. Is it now packaged into another installation package like the Fusion Middleware or something like that, do you know?

    I am particularly interested in in using Oracle Fedlet based on the documentation I have read which talks about the simple implementation and small footprint qualities.

    Any pointers you can provide would be very helpful.

    Thank you,
    M. Reddy

      I’ll need to check to see if they have moved the link. But it’s still available as far as I know. I’ll update the post if I find the new URL.
