Hi there @robert.compton
Apologies in our delayed response, and thanks for asking about SSO via Crowd with Octopus.
We don’t currently support Crowd directly, however we have an open source, extensible architecture for implementing providers. With a little work, it is possible to provide your own, there are a few OpenID connect based providers in our public github repository. In particular, the Okta provider might be a great place to start.
The entrypoint into the documentation on this is here: https://octopus.com/docs/api-and-integration/server-extensibility/authoring-an-octopus-deploy-server-extension
There is a user voice suggestion here that might be of interest too.
Hope this helps,
