Hey @simon !
Thanks for all the feedback, I’ll give it a try in my test setup as running such hack in a production environment can be risky! Grant me time till tomorrow, i’ll share my findings here.
buttons in wp-login.php isn’t that big of a concern for me, I basically need some way to embed a wordpress navigation menu entry that quotes link/login to discourse (forum) account and clicking on that does the whole SSO magic for any user without a hiccup.
Let me know if there’s a starting point to it. maybe some sort of webhook or url that could be set there to automate the process?
I searched the wordpress support and found nothing relevant, but I’ve seen theme developers hardcoding things such as facebook login so maybe there is some sort of possibility to implement this if we take the right approach?
