Hi there I have been using ZP in combination with WP for 10 years, I have never managed to get a fully working SSO.

I think I used this extension a couple of years ago:

It has not been updated in over tree years though.

My question: has anyone managed to get the SSO working? Any suugestions?

Kind regards

We also have a federatedLogin plugin. That however does not support WordPress but some services like Google. You possibly can extend it to support WordPress.

I have to admit I have never used it and it was written by a former contributor so I cannot really tell if is working at all.
