Dynamics 365 :The user authentication passed to the platform is not valid

Recently, A message "the user authentication passed to the platform is not valid" was thrown while opening the report in CRM.

I have no idea what is going on, thus i turned on the CRM tracing and i found that the was something wrong with Report server.

Solution

1. Open Reporting Services Configuration Manager, and the service was stopped.

 

2. After some investigation, finally i found out the reason , it was because AD team changed the admin password without informing us.

3. Reactivate the Service and changed the password for Service Account

4.  Result

I hope this will save you some time and understand the reason behind it. Happy CRM-ing.
