We have subscribed for enterprise edition. We would like to inquire about the implementation of Single Sign-On (SSO) using SAML set up through Google. We have successfully tested the SSO login and are able to display profiles for clients. However, when attempting to activate the Single Sign-On server in Pritunl, we encountered an error message on server side stating “invalid SSO token”, and in the client side “Connection failed”. Could you kindly assist us with this matter?

The [**Google single sign-on**](https://docs.pritunl.com/docs/google) documentation has information on configuring Google single sign-on. This is the only supported way to configure it.
