In this post we will see unable to run SSRS reports from other domain users and gives an error The Default Value expression for the report parameter ‘UserTokenSIDs’ contains an error: The user name or password is incorrect. (rsRuntimeErrorInExpression)"
Below are details steps to fix the issue.
Role Based Administration in MECM Current Branch, MECM will switch a flag in the registry. The registry key is HKLM\Software\Microsoft\SMS\SRSRP, value name is "EnableRbacReporting" set value to 0,

No user from trusted domains can run the reports. We have to set the value back to 0 and restart the report server for it to work again. But after sometime, SCCM set the value back to 1 and we are lost again.
We can change the value in WMI on the server where SSRS is installed.
