Hi Adrian Morgan is right in saying that an external IdP would solve many of your user management problems, but then of course, you will be using federated keystone which you seem reluctant to do :-) However, if you have an IdP under your full control then you can allow users to self register and reset their passwords.
The next problem you will then face, is user authorisation - as opposed to user authentication. The VO roles blueprint that we have worked on addresses the authorisation problem. So when you are ready for this, let me know regards David On 15/01/2015 00:42, Morgan Fainberg wrote: >> >> On Jan 13, 2015, at 9:06 PM, Adrian Turjak <adri...@catalyst.net.nz> wrote: >> >> Hello openstack-dev, >> >> I'm wondering if there is any interest or need for an open-source user >> registration and management service for people using OpenStack. >> >> We're currently at a point where we need a way for users to sign up >> themselves, choose their own password, and request new users to be added >> to their project.
