Ok, I think I get a better understanding now. Thanks for helping me out.
It did work with the generated link under a WP post. But it wasn’t working for a custom link I added because I was sending the click right to the home page of the forum instead of the sso session handler exemple.com/session/sso?return_path=exemple.com.
This link was on my WP main menu, and I want current users to be automatically logged in if they have an account but I want first time visitors and not logged in user to still be able to access the forums without being redirected to the login page.
I guess I’m going to have to write up a bit of code to make that happen.
If you know of a way of doing that with a current setting, let me know.
In any case, thanks again for helping me better understand this.
cheers
