# ldap PoC updates Now users, groups, and group membership are populating from ldap automatically on login (with auth backed by ldap also)! I'll be sharing my configs for both ldap and how to configure django-auth-ldap <https://django-auth-ldap.readthedocs.io/en/latest/example.html> here soon in an organized way. This was done with django-auth-ldap and 0 customization to pulp code. It's 100% enabled through settings so this work is more of an approach we can document for users that they can enable and not a feature Pulp ships itself.
# django-admin progress Thanks to @alikins existing PRs, I got django admin enabled and able to view/edit users, groups, group membership, and permissions at both the user and group levels. This is important because this will be the primary mechanism of administrators. This part is looking good. # new resources to help us out Through collaboration with @ttereshc and someone off list named @adelton (who actually authored this reference approach <https://www.adelton.com/django/external-authentication-for-django-projects> I referenced early on in this exploration), this very cool repository of testing tools was identified: https://github.com/adelton/webauthinfra It has a treasure trove of testing containers which Pulp devs in the future can test against. It keeps the user/group check in the apache which is fine alternative to the django-auth-ldap approach above. Pulp doesn't have to choose, it could work with either just configured differently. The pending PoC outline will go over these alternative approaches in detail. # Next Steps: back to the PoC itself Now that we have demonstrated good options of external users/groups/membership loading into Pulp we can confidently move back to finishing the RBAC PoC itself. I've started back into this. So the remaining work are the two steps below: 1. Finish the PoC that uses RBAC to restrict remotes, sync, and repository content modification. Currently I prototyped restriction of operations on Remotes, but I need to replicate the access policies to Repositories and Sync next. 2. Write it up and share it. 3. Schedule public meeting to review it (targeting next-week) On Fri, Jun 19, 2020 at 5:09 PM Brian Bouterse <bmbou...@redhat.com> wrote: > I got the LDAP users both authenticating and importing into Pulp!
