SP-initiated SAML problem

Hi!
I am trying to setup saml2 authentication + authorization mechanism for JupyterHub
with Oracle Access Manager.

I used the official library jupyterhub-samlauthenticator, found on the jupyterhub’s wiki.

I got stuck on the empty SAMLRequest problem and after various investigations I found that
this library (currently at version 0.0.9) seems to have a problem with the SP-Initiated call(repo issues 33, 17, 4).

Is there any way to fix this or at least a workaround?

thank you all

That authenticator isn’t maintained by the core JupyterHub team, so if you don’t get an answer on this forum you might want to ask the maintainers directly.
