Communication Task Authentication failed

L0 Member


I want users to authenticate in Cortex XSOAR before answering the form sent by mail like explained here


The AD authentication instance seems to work, and when I try to login I can see on the AD side that the request is made and has the status succes.

I have checked Use this instance for external authentication only in the instance config.


But I cannot log in. In the Audit Trail I have: error - Could not authenticate user for external action.


In the documentation it is writen "For the Active Directory integration, enter the relevant groups for the external users.".

The only thing group related I can see is the check box: Auto populate groups


Thank you
