I have yet to see the wp-discourse using discourse as sso provider functionality in the wild and would love to do so. Anyone have a link?
I'm very interested in allowing members to log in via discourse (and consequently via discourse social logins using twitter, facebook etc) but following the discussion about it on github it seems my use case is not supported.
Upon login, if the account does not already exist in wordpress, I'd like to kick the user over to the signup form on wordpress, which has some customizations on our side to deal with synchronization of profile details from wordpress to discourse upon signup, along with a custom welcome PM. It works quite well and I don't want to mess with it too much. I suspect this is not such a rare setup.
I don't think your functionality offers support for this type of setup so far.
Maybe I need to find a different wordpress plugin to handle social logins even if it means bypassing discourse's quite amazing social login functionality which would be a shame. If anyone has done this already and has tips, I'd appreciate it.
