Authentik - OpenCloud integration

Sat, 29 Aug 2026 00:00:00 +0000

I’ll get straight to the point. The content of this post is to show you how to integrate OpenCloud’s OIDC with Authentik as of August 2026.

Initial incompatibility issues

There is some good documentation on Authentik’s website that explains how to set up both sides of the equation. There are a couple of quirks with OpenCloud’s implementation of OIDC.

The first one is that each type of OpenCloud client needs its own OIDC client as well (or, in Authentik’s case, a provider).
The client IDs are for some reason hardcoded for each OpenCloud client, so you’d need to match those on Authentik’s end.

That could be fine if you are using an SSO service other than Authentik, but in our case we hit a design limitation on Authentik’s side because it allows only a single provider per application. If you want to use just one OpenCloud client, then that would be OK, but I find it unlikely. The above linked documentation from Authentik’s webpage shows two guides, one for a single client and another if you want to utilize all four available OpenCloud clients (web, desktop, Android, iOS). For both cases, following the documentation should work.
