Hi  

 

I am trying to set this up for a webtop. I am on version 16.0.11 Build 0.9.6. I authenticate using LDAP first then use the irule event and oauth client before assigning the resources. After successfully authenticating to LDAP, I get redirected to the Duo portal with the error " {"error": "invalid_client", "error_description": "The supplied client_assertion is not a valid JWT"} " I have double-checked my configuration and looks ok. so not sure what I am missing. can you help?

 

Thanks
