What are the minimum Remote Powershell permissions required for a user?

I am writing a web service which needs to execute remote powershell in logged-on user context.

The application works fine if the logged-in user is a member of administrators group on remote machine, else the RunspaceFactory.CreateRunspace API fails with PSInvalidOperationException.

I have tried adding user to remote powershell users (using Set-PSSessionConfiguration), which I believe is the only required permission to run remote powershell.

Also, when I try this in a C# console application it works fine. I see the issue only with my web service.

I have also tried setting aspnet.config to allow flow of impersonation but still no luck.

<configuration><runtime><legacyImpersonationPolicyenabled=”false”/><alwaysFlowImpersonationPolicyenabled=”true”/></runtime></configuration>

I want to know if there are any additional settings required for IIS or ASP .NET to make it work?

Warm Regards
