SSO problem - how to debug?

(Ted Strauss) #1

I have recently migrated my discourse onto a new server.
I now have inconsistent results from SSO logins.
One user (maybe more) is shown a login prompt when I have configured SSO to authenticate to the site directly. We have tried clearing cache, incognito/different browser, force logout of the user by admin. It works fine for several other users.

Here are the SSO settings on the back end. I can provide the working PHP code of my other site handling the request.

My question - besides help-me-fix-it! - is how can we debug this issue with dev tools. I’m looking in the network tab of chrome dev for where the authentication is being handled. Where else can I see why this might be failing?
