Hi, I’m excited about the SSO potential of st.login(). We have a Streamlit app that’s running on a linux vps with https using dokploy and traefik. We also have Authentik running as our OIDC provider and want to use it with the app.
I changed the authentication strategy from using streamlit-authenticator, which was doing OK, to using st.login, following the api documentation guidance. In particular, I created the [auth] block of declarations in the secrets.toml file as described, for example, here.
When the app is run we get the error message st.user has no attribute “is_logged_in”. This is in response to the code if not st.user.is_logged_in:. Checking, we find that st.user is empty.
We’ve checked our uri, callback, etc. There seems to be nothing wrong. We find no useful information in the server log (see below). Is there debugging information somewhere?
Help will be appreciated!
