Hi Simon, I have been looking into the various bits and pieces of info provided but can’t figure out how to connect the dots.
I’ve created the corresponding group names as user roles in WP, but I don’t know what it means to   “add the Discourse group names to the SSO payload. You can do this by hooking into the  wpdc_sso_params  filter,” ---- like you mentioned in @apautler Andrew’s post.
Further down in that post, Andrew mentions he found ‘the right code’ - which seems to be what i need as well… but i have no idea where to stick it:
Would appreciate some further insight, thank you!
Dani
