i am self hosting a gitlab instance in a kubernetes cluster. My configuration is done via helm chart. Now, I want to use shibboleth as a sso provider. The documentation is a little bit lacking on the shibboleth site. https://docs.gitlab.com/ee/integration/shibboleth.html
To my progress so far, via git.example.com/Shibboleth.sso/Session i already get Attributes, Logging in and Out is already working but via https://git.example.com/users/auth/shibboleth/callback, like it should be according to the documentation, i simply get a "You need to sign in or sign up before continuing."
Alternately to this, the saml approach according to https://docs.gitlab.com/ee/integration/saml.html?tab=Helm+chart+%28Kubernetes%29
Via the url: https://git.example.com/users/auth/shibboleth/callback
I get the following error:
"Could not authenticate you from SAML because "Saml response missing".
Does anyone has a clue, at least how to start troubleshooting? Does anyone have experience in using shibboleth and kubernetes gitlab via helm chart?
Cheers
