Unable to login via IdentityProvider Initiated

[acelinkio]

Description

I unable to login via identity provider (IDP) initiated. After clicking on launch icon inside of my identity provider, I am taken to the SP initiated login screen for Vikunja, https://tasks.mydomain.tld/login, instead of being logged into the application. Ideally that would automatically sign in to Vikunja.

Instead additional click is needed to start the service provider (SP) initiated login, which does work correctly.

This works as intended. If there are multiple auth methods, users need to be able to choose which one they use.

If you set the link to https://tasks.mydomain.tld/?redirectToProvider=true and have local auth disabled and have only one auth provider, it will automatically redirect the user to your Auth provider when they are not logged in.

This does not happen automatically because then users would be logged in again directly after they logged out.
